Background: Oxidative and nitrosative stress caused by drug metabolism may be a trigger for keratinocyte apoptosis in the epidermis seen in toxic epidermal necrolysis (TEN) and Stevens Johnson syndrome (SJS). Aims: To estimate oxidative damage in the serum and to examine the role of nitric oxide in mediating epidermal damage in patients with TEN and SJS. Materials and Methods: A prospective study was conducted among TEN and SJS patients and controls in a tertiary care center between January 2006 and February 2010. Patients with a maculopapular drug rash without detachment of skin constituted the control group 1 (drug exposed). Patients without a drug rash constituted the control group 2 (drug unexposed). The serum values of protein carbonyls, malondialdehyde, conjugated diene and nitrates were measured. Two-group comparison with the non-parametric Mann-Whitney U test was used. Significance of differences if any was established using Pearson's Chi-square test. Results: Ten patients in the SJS-TEN group (study group), 8 patients in control group 1 and 7 patients in control group 2 were included. More than one drug was implicated in 4/10 patients in group 1 and 3/8 patients in group 2. SCORTEN of 0, 1 and 3 at admission were seen in 2, 6 and 2 patients, respectively. The serum values of protein carbonyls, malondialdehyde, conjugated diene and nitrates were not significantly increased in the study group when compared to the controls. Conclusions: There was no elevation of oxidative stress markers in patients with TEN and SJS as compared to the control population.

Background: Psoriasis is a chronic inflammatory disease driven by exaggerated production of pro-inflammatory cytokines and interleukins. Various genetic polymorphisms including IL-1 are implicated in pathogenesis of psoriasis. The exact role of IL-1 gene polymorphisms and their interaction with NFκB is not yet determined. We aimed to study various genetic polymorphisms of IL-1 in psoriasis and their influence on NFκB and histopathological features. Materials and Methods: 112 newly diagnosed cases of psoriasis vulgaris were included in this prospective study. Histology was done on sections and genotyping was done for the IL-1β and IL-1 receptor antagonist (IL-1RA) genetic polymorphisms. In addition, NFκB immunostaining was performed on 89 sections and the intensity of staining was evaluated in the epidermis, basal cells, and the lymphocytes. Results : A strong association of IL-1β 511 C/T polymorphism was found with both genotypes and alleles in psoriasis. A strong correlation was also detected between the IL-1β genotype and the grade of NFκB immunostaining in the epidermis (P = 0.012). The grade of NFκB lymphocyte staining showed a strong correlation with the IL-1RA genotype (P = 0.025) but not with the IL-1β genotype (P = 0.226). The genetic polymorphisms did not show any correlation with the histological features. Conclusions: IL-1 genetic polymorphisms may not play a very direct role in pathogenesis of psoriasis. However, their interaction with NFκB appears to be a significant factor in this direction as NFκB is activated by pro-inflammatory genetic polymorphisms and therefore may influence the severity of psoriasis.

Background: Lichen planus (LP), a T-cell-mediated inflammatory disorder, wherein inflammation produces lipid metabolism disturbances, is linked to increase in cardiovascular (CV) risk with dyslipidemia. Increased reactive oxygen species and lipid peroxides have also been implicated in its pathogenesis. Aim and Objective: The aim of the study was to evaluate the status on lipid disturbances, oxidative stress, and inflammation in LP patients. Materials and Methods: The study was initiated after obtaining Institutional Ethics Committee permission and written informed consent from participants. The study included 125 patients (74 LP patients and 51 age and sex-matched controls) visiting the outpatient clinic in the dermatology department of our hospital. Variables analyzed included lipid profile, C-reactive protein (CRP), malondialdehyde (MDA), and catalase (CAT) activity. Results: Analysis of lipid parameters revealed significantly higher levels of total cholesterol (TC), triglycerides, and low-density lipoprotein cholesterol (LDL-C) along with decreased levels of high-density lipoprotein cholesterol (HDL-C) in LP patients as compared to their respective controls. LP patients also presented with a significantly higher atherogenic index that is, (TC/HDL-C) and LDL-C/HDL-C ratios than the controls. A significant increase in CRP levels was observed among the LP patients. There was a statistically significant increase in the serum levels of the lipid peroxidation product, MDA and a statistically significant decrease in CAT activity in LP patients as compared to their respective controls. A statistically significant positive correlation (r = 0.96) was observed between serum MDA levels and duration of LP whereas a significantly negative correlation (r = −0.76) was seen between CAT activity and LP duration. Conclusion: Chronic inflammation in patients with LP may explain the association with dyslipidemia and CV risk. Our findings also suggest that an increase in oxidative stress and imbalance in the antioxidant defense mechanisms in LP may play a role in the pathogenesis of LP.

Context: Lichen planus is a psychosomatic disease. Higher frequency of psychiatric symptoms, poor quality of life, higher level of anxiety and neuroendocrine and immune dysregulations, all these factors, will enhance the exacerbation of the disease. Aims: The present study was to assess depression, anxiety and stress levels in patients with oral lichen planus. Methods: The psychometric evaluation using the Depression Anxiety Stress Scale (DASS)-42 questionnaire was carried out, by the same investigator on all members of group 1 (Oral Lichen Planus) and group 2 (Control). DASS-42 questionnaire consists of 42 symptoms divided into three subscales of 14 items: Depression scale, anxiety scale, and stress scale. Statistical Analysis Used: The Student t test was used to determine statistical difference for both the groups and to evaluate for significant relationships among variables. Results: Psychological assessment using DASS-42 reveals lichen planus patients showed higher frequency of psychiatric co morbidities like depression, anxiety and stress compared to control group. Conclusions: This study has provided evidence that the DASS-42 questionnaire is internally consistent and valid measures of depression, anxiety, and stress. Psychiatric evaluation can be considered for patients with oral lichen planus with routine treatment protocols are recommended. DASS-42 Questionnaire can also be used to determine the level of anxiety, stress and depression in diseases of the oral mucosa like recurrent apthous stomatitis, burning mouth syndrome and TMD disorders.

Background: Basement membrane (BM) is a thick sheet of extracellular matrix molecules, upon which epithelial cells attach. Various immunohistochemical studies in the past have been carried out but these advanced staining techniques are expensive and not feasible in routine laboratories. Although hematoxylin and eosin (H-E) is very popular among pathologists for looking at biopsies, the method has some limitations. This is where special stains come handy. Aims and Objectives: The aim of the present study was to demonstrate and compare the efficacy of H-E, periodic acid Schiff (PAS) and fluorescent periodic acid-acriflavine staining techniques for the basement membrane and to establish a histochemical stain which could be cost effective, less time consuming, and unambiguous for observation of the basement membrane zone. Materials and Methods: A total number of 40 paraffin-embedded tissue sections of known basement membrane containing tissues including 10 - Normal oral mucosa (NOM) and 30 - oral lichen planus (OLP) were considered in the study. Four-micron-thick sections of each block were cut and stained with H-E stain, PAS and fluorescent periodic acid-acriflavine stain. Sections were evaluated by three oral pathologists independently for continuity, contrast and pattern. Results: Though all the three stains showed favorable features at different levels, acriflavine stain was better than the other stains in demonstrating BM continuity, contrast and also the pattern followed by PAS stain. Acriflavine stain was the better in demonstrating a fibrillar pattern of a BM. Acriflavine stains a BM distinctly and is less time consuming and easy to carry out using readily available dyes as compared to other stains. Conclusion: The continuity and contrast along with the homogenous pattern and the afibrillar pattern of the BM was better demonstrated by acriflavine followed by the PAS stain.

Lichen planus is a common papulosquamous disorder affecting about 1-2% of the population, neoplastic transformation of cutaneous lichen planus lesions occurs very rarely. A 40 year old female patient presented with a 1 year history of developing multiple, itchy, pigmented lesions over both lower legs which gradually spread to involve the whole body. A few tense bullae were seen on the extremities. An erythematous fleshy lesion was seen on the upper aspect of the left buttock. Skin biopsy from a plaque on the right forearm showed features suggestive of lichen planus. Skin biopsy of a bullae showed a sub epidermal bulla filled with a mixed inflammatory infiltrate. Direct immunofluorescence revealed no immunoreactants along the basement membrane zone. A diagnosis of erythrodermic lichen planus with bullous lichen planus was made. Biopsy of fleshy lesion of left buttock revealed a moderately differentiated squamous cell carcinoma. Erythrodermic lichen planus with bullous lesions and secondary squamous cell carcinoma; these occurences in a single patient is extremely rare and has not been previously reported to the best of our knowledge.

Background: Acne is a common disorder among adolescents and young adults causing a considerable psychological impact including anxiety and depression. Isotretinoin, a synthetic oral retinoid is very effective in the treatment of moderate to severe acne. But there have been many reports linking isotretinoin to depression and suicide though no clear proof of association has been established so far. Objective: To determine whether oral isotretinoin increases the risk of depression in patients with moderate to severe acne. Materials and Methods: One hundred and fifty patients with moderate to severe acne were treated with oral isotretinoin 0.5 mg/kg/day for a period of 3 months. Their acne and depression scoring was done at baseline and then every month for the first 3 months and then at 6 months. Results: We found that the acne scoring reduced from 3.11 ± 0.49 to 0.65 ± 0.62 (P = < 0.001) at the end of 3 months. Also, the depression scoring decreased significantly from 3.89 ± 4.9 at the beginning of study to 0.45 ± 1.12 (P < 0.001) at the end of 3 months. Both the acne and depression scores continued to remain low at the end of 6 months at 0.5 ± 0.52 (P = < 0.001) and 0.18 ± 0.51 (P = < 0.001), respectively. Conclusions: Our study proves that oral isotretinoin causes significant clearance of acne lesions. It causes significant reduction in depression scores and is not associated with an increased incidence of depression or suicidal tendencies.

Background and Aim: This single-center observational cross-sectional study has been done in an attempt to find out the prevalence of various skin manifestations in diabetes patients (DM) and their correlation with diabetes control and complications. Materials and Methods: Skin manifestations present over 12 months among those attend diabetes clinic were included in the study. Apart from demographic data and type, patients were also screened for micro vascular complications and control of diabetes over last 3 months. Results and Discussion: Sixty (n = 60) diabetes patisents (Type 1 DM, 9 patients and Type 2 DM 51 patients) have been found to have various skin lesions. Thirty-one (51.67%) patients presented with infectious conditions, vascular complications were present in 21 (35%) and dermatomes belonging to the miscellaneous group were present in 50 (83.33%) patients. Pyoderma, diabetic dermopathy, and pruritus without skin lesions were found to be most common manifestations in infective, vascular and miscellaneous group, respectively. Higher level of HB1 _AC was found in patient with diabetic bulla (10.5 ± 0), scleredema (9.75 ± 0.77), lichen planus (9.3 ± 1.6), and acanthosis nigricans (9.15 ± 0.89). Patients with psoriasis and vitiligo had statistically significant lower level of glycosylated hemoglobin (P =< 0.001 and 0.03, respectively). However, no association of any kind of skin manifestation with DM with other microangiopathic complications was found in this study.

The treatment of vitiligo is derisory since the pathogenesis of vitiligo is not clear at present. Most conservative treatments are difficult to approach satisfactory therapy. So transplantation is the only way left when the disease becomes insensitive to those conservative treatments. Here we describe an 18-year-old patient who developed vitiligo, which was triggered by graft-versus-host disease after a allogeneic bone marrow transplantation for the treatment of Hodgkin's lymphoma from his sister. In the following treatment to vitiligo, the patient successfully performed the transplantation of autologous uncultured melanocyte on the premise of poor reaction to other conservative methods. We infer that transplantation can be a treatment of the vitiligo after allogeneic bone marrow transplantation.

Background: A number of treatments for reducing the appearance of acne scars are available, but general guidelines for optimizing acne scar treatment do not exist. The aim of this study was to compare the clinical effectiveness and side effects of fractional carbon dioxide (CO ₂ ) laser resurfacing combined with punch elevation with fractional CO ₂ laser resurfacing alone in the treatment of atrophic acne scars. Materials and Methods: Forty-two Iranian subjects (age range 18-55) with Fitzpatrick skin types III to IV and moderate to severe atrophic acne scars on both cheeks received randomized split-face treatments: One side received fractional CO ₂ laser treatment and the other received one session of punch elevation combined with two sessions of laser fractional CO ₂ laser treatment, separated by an interval of 1 month. Two dermatologists independently evaluated improvement in acne scars 4 and 16 weeks after the last treatment. Side effects were also recorded after each treatment. Results: The mean ± SD age of patients was 23.4 ± 2.6 years. Clinical improvement of facial acne scarring was assessed by two dermatologists blinded to treatment conditions. No significant difference in evaluation was observed 1 month after treatment (P = 0.56). Their evaluation found that fractional CO ₂ laser treatment combined with punch elevation had greater efficacy than that with fractional CO ₂ laser treatment alone, assessed 4 months after treatment (P = 0.02). Among all side effects, coagulated crust formation and pruritus at day 3 after fractional CO ₂ laser treatment was significant on both treatment sides (P < 0.05). Conclusion: Concurrent use of fractional laser skin resurfacing with punch elevation offers a safe and effective approach for the treatment of acne scarring.

Background: The spectrum of pyoderma changes constantly, and so does the antibiotic susceptibility pattern. Aims: This study was done to assess the magnitude and clinical patterns of pyodermas, their causative micro-organisms, and the antibiotic susceptibility patterns. Materials and Methods: Five hundred consecutive, clinically diagnosed and untreated cases of pyoderma, attending the Dermatology OPD of RNT Medical College and MB Government Hospital, Udaipur, from October 2010 to September 2011 were the subjects of this study. A detailed clinical examination, and relevant investigations including bacterial culture and sensitivity, were carried out and recorded. Statistical Analysis: For statistical analysis of data, the software 'EPI-INFO Version 6' was used, and Chi-square (χ²) test was applied. Results: Of 19576 cases attending skin OPD during the study period, pyoderma was seen in 500 patients; the incidence being 2.55%. Males outnumbered females. The highest number of cases (109; 21.8%) was observed in 1st decade. Lower extremities were the commonest site of predilection. Primary pyodermas outnumbered secondary pyodermas. Furuncle (136; 27.2%) and infectious eczematoid dermatitis (62; 12.4%) were the commonest entities among primary and secondary pyoderma respectively. Staphylococcus aureus was the commonest causative agent in both primary and secondary pyoderma. It showed high susceptibility to amoxycillin + sulbactam, aminoglycosides and cefoperazone, moderate susceptibility to linezolid, while low susceptibility to fluoroquinolones and cephalexin. Conclusion: Such studies help to assess the changing trend of bacterial infections, their causative organisms and antibiotic susceptibility pattern.

A 68-year-old man, a known case of hypertension, coronary artery disease and old cardiovascular accident with right-sided hemiplegia, came with the chief complaints of a large cauliflower like growth with pus discharge on the left heel since 15 years. The patient had sustained a penetrating injury by a thorn on the left heel region few days before the lesion appeared. Dermatological examination revealed a single verrucous lesion measuring 7 × 7 cm on the left heel region associated with discharge of foul smelling cheesy material. There was also a enlarged right inguinal lymph node which was non-tender, firm, measuring 2 cm in diameter with normal overlying skin. X-ray left ankle was done which showed some soft tissue swelling. A skin biopsy showed hyperkeratosis, acanthosis and parakeratosis. Elongated rete ridges with keratinocyte hyperplasia, forming a large mass pressing on the underlying dermis were seen. There was formation of multiple large keratin filled invaginations and crypts. No atypical cells were seen. Based on history, clinical examination and investigations, a diagnosis of epithelium cuniculatum type of verrucous squamous cell carcinoma was made. A wide excision with a flap cover was performed in consultation with the oncosurgeon and the excision sample was sent for histopathological re-examination, which confirmed the diagnosis of epithelioma cuniculatum.

Jellyfish envenomation can present with local cutaneous lesions both immediate and delayed. While the immediate reaction is toxin mediated, an immune mechanism is responsible for the delayed eruptions. This is a report of a mother and child who developed identical papular lesions in a bizarre, linear distribution after coming in contact with jellyfish almost simultaneously while on holiday. Histology showed focal basal cell degeneration along with peri-vascular and peri-appendageal lympho-mononuclear infiltrate. Both patients responded well to topical tacrolimus.

X-linked ichthyosis is a rare form of dermatological disease and when it presents as erythroderma it is even rarer. History of consanguineous marriage and prolonged labor during birth of patient, generalized scaling which gets better in summer months, flexural involvement, cryptorchidism made a diagnosis of X-linked ichthyosis. We report this case because of its rarity as erythroderma.

Klinefelter syndrome (KFS) is the most common non-heritable sex chromosome anomaly caused by nondisjunction during cell division and contains two or more X chromosomes. More than two third of all cases are homogenous (47XXY) and the remaining are mosaic (46XY/47XXY). Lower limb ulcers are frequently observed and attributed to impaired fibrinolysis. A case of KFS with post acne scars and leg ulcers is presented. The rarity of acne in this syndrome is explained by the phenomenon of mosaicism.

A 75-year-old man presented with a slowly growing mass at the right side of the base of the tongue for 4 months. The mass was painless initially but had become very painful during preceding 4 weeks. On examination a 3 cm diameter, oval swelling was observed at the right side of the base of the tongue. It was firm in consistency, slightly tender, non-ulcerative, and with irregular surface. A deep incisional biopsy was taken from mass under general anesthesia. Histopathology report identified the mass consistent with neurofibroma. It featured typical pallisading arrangement of fascicles of spindle-shaped cells and there was no evidence of malignancy. An absence of Verocay body and thick hyalinized vessels ruled out Schwannoma. No similar lesions were found in any other part of the patient's body. He exhibited no skin pigmentation, no hearing deficit, and no evidence suggestive of any systemic disorders that might have been attributable to the tongue base neurofibroma. His family history was also negative. Thus, a diagnosis of isolated neurofibroma of the tongue was established. The patient was advised excision of the mass but he refused and lost in follow up.

Subcutaneous Zygomycosis is a rare opportunistic fungal infection caused by Basidiobolus ranarum. Though this entity is endemic in South India, limited numbers of cases have been reported from this part of the country. We report a case of subcutaneous zygomycosis in a 25 year old lady who presented with a nontender, firm to hard swelling over the upper-left arm. Finger was easily inserted below the indurated edge. Histopathology revealed suppurative granuloma with aseptate hyphae. Patient responded excellently to saturated solution of potassium iodide in subsequent visits.

Colocalization of diseases in dermatology has always remained elusive and a puzzle, difficult to unscramble. Co-localization of two rare and disparate dermatoses has been reported on several occasions. Lichen planus (LP) has been described to colocalize with several dermatoses. We report here a case of LP hypertrophicus co-localizing with epidermoid cysts on the scrotum of a 35-year-old man for the unusual site and association.

Lupus vulgaris is a chronic paucibacillary form of cutaneous tuberculosis occurring in a person with a moderate to high degree of immunity. It commonly occurs over the buttocks and trunk in India. Involvement of the genitalia is uncommon, and lesions involving the penis, extremely rare with few cases reported worldwide. There also exists a confusion regarding nosology of tuberculosis of the genitalia. A brief discussion and review of literature are being discussed along with the report of a case of genital tuberculosis involving the glans penis.

Spindle-cell hemangioendothelioma (SCHE) comprise a rare subset of vascular tumors, and here, we describe such a case and review the clinical presentation, patho-physiology, differential diagnosis of these tumors to promote early identification and discussion guidance. A 25-years-old male patient presented with multiple painful elevated swellings of both left upper and lower extremities for last 15 years without any systemic involvement. After excluding close differential diagnosis by relevant investigations an excisional biopsy was performed. Based on clinical, radiological and histopathological findings, diagnosis of SCHE was made and full thickness excision and skin grafting were performed. The case is reported due to its rarity and adds our knowledge to the existing literature.

Background: Seborrheic dermatitis is a common chronic inflammatory skin condition that can have a negative impact on a patient's quality of life. Few studies have been conducted to assess the clinical characteristics of the disease and quality of life of the patients, especially in tropical countries. Aims and Objectives: The aim of this study was to demonstrate the clinical characteristics and quality of life of patients with seborrheic dermatitis in Thailand. Materials and Methods: A cross-sectional study was performed at a university-based hospital and tertiary referral center in Bangkok, Thailand. The validated Thai version of the dermatology life quality index (DLQI) was used to evaluate patients' quality of life. Results: A total of 166 participants were included. One hundred and forty-seven patients (88.6%) experienced multiple episodes of the eruption. The mean of outbreaks was 7.8 times per years, ranging from once every 4 years to weekly eruption. The most common factor reported to aggravate seborrheic dermatitis was seasonality (34.9%), especially hot climate. The mean (SD) of the total DLQI score was 8.1 (6.0) with a range of 0 to 27. There was no statistically significant difference between the two DLQI categories regarding duration of disease, extent of involvement, symptoms or course of the disease. Conclusion: Although mild and asymptomatic, seborrheic dermatitis can have a great impact on the quality of life. Youth, female gender, and scalp lesions were significantly associated with higher DLQI scores.

Background: Erythema annulare centrifugum (EAC) is an inflammatory dermatosis with unknown etiology. It is usually self-limited, but chronic disease may be difficult to treat. We observed incidentally the therapeutic effect of erythromycin for EAC among patients taking erythromycin for other diseases. Aim: To evaluate the treatment response of erythromycin for EAC. Materials and Methods: During the study period, from July 2007 to February 2011, all patients with EAC were assigned to erythromycin stearate tablet 1000 mg per day for two weeks. EAC was diagnosed by a constellation of clinical and pathological findings. The efficacy (before and after the treatment) was assessed clinically by one dermatologist and photographically by two blinded dermatologists. Secondary outcomes included adverse drug effects and recurrence. Results: Eight patients were enrolled in this study. Most patients had chronic relapsing disease with poor response to previous treatment. All the patients showed rapid response with profound reduction in the size of lesion and erythema two weeks after initiation of erythromycin treatment. The response was so obvious and complete that a coincidental response was less likely. Three patients had recurrence of disease and they tended to have more extensive lesions. Readministration of erythromycin was effective. All patients tolerated the treatment well. Conclusion: Our study documented erythromycin as a safe and cost-effective treatment for EAC.

Background: Acral or acrofacial vitiligo (AFV) with bilateral lesions over the extremities and face is considered as a transitional form that may progress to generalized vitiligo. Oral and genital mucosal lesions are often integral to this pattern. Lichen sclerosus (LS) in a milder expression, results in oral and genital vitiligoid depigmentation without textural changes and thus needs to be differentiated from AFV. Materials and Methods: We reviewed 217 cases of AFV recorded over a period of 12 years. Results: One hundred and sixteen cases had associated oral/genital lesions. Among these, 15 patients demonstrated typical clinical as well as histological features of LS. Discussion: Coexistence of typical LS essentially among oral and genital lesions of acral vitiligo suggests that acral vitiligo might be a distinct sub-group of NSV. Since both the diseases have an autoimmune basis, the co-existence may be explained by epitope spreading, as a result of interface dermatitis seen in vitiligo. In addition, the possibility of a common genetic predisposition needs to be explored.

Background: Atopic dermatitis is a distinct age-related clinical entity. Its etiopathogenesis is largely insubstantial. Nevertheless, it seems to be an outcome of interplay of maternal and inheritance, pregnancy/intrauterine and environmental factors. Besides, immune dysregulation, and nutritional supplements also play essential roles. Its diagnosis has been perpetuated by three or more major/minor criteria. Objectives: An endeavor to study its demographic and clinical pattern in contemporary prospective. Materials and Methods: 100 fresh patients of atopic dermatitis, diagnosed on the basis of an established three or more major and minor criteria, salient presentations of which were recorded in a preset proforma, which also recorded age, duration, age of onset, and sex. Serum immunoglobulin E (IgE) levels were determined by conventional technique. The data thus obtained was analysed to study its clinical pattern and to correlate its severity to IgE levels. Results: Its overall (new and old) prevalence was 0.98%, while that of new patients was 0.24%. 83 (83%) were in the age group of 2-12 years, of which 54 (83.1%) were males and 29 (82.9%) were female, of which 70 (70%) had urban, while 30 (30%) had rural background. Its duration varied from 8 to 192 weeks, with a mean of 76 weeks, and a standard deviation of 21.42 weeks [76 ± 21.42]. Conclusion: Atopic dermatitis is a discrete, overt, age and IgE-related entity frequently displaying varying demographic and clinical connotation.

Background: Melasma is one of the most common and distressing pigmentary disorders presenting to dermatology clinics. The precise cause of melasma remains unknown. It is notably difficult to treat and has a tendency to relapse. Its population prevalence varies according to ethnic composition, skin phototype, and intensity of sun exposure. Due to its frequent facial involvement, the disease has an impact on the quality of life of patients. Aims: To study the clinico-epidemiological pattern, dermascopy, wood's lamp findings and the quality of life in patients with melasma. Settings and Design: Observational/descriptive study. Materials and Methods: Patients with melasma were screened. History, clinical examination, Wood's lamp examination (WLE) and dermoscopy were done. Severity of melasma was assessed by the calculating melasma area severity index (MASI) score. Quality of Life (QOL) was assessed using MELASQOL scale with a standard structured questionnaire. Statistical Analysis: Descriptive, Chi-square test and contingency coefficient analysis. Results: In 140 cases of melasma, 95 (67.9%) were females and 45 (32%) were males. Common age group affected was 31-40 years (65%). Majority were unskilled workers with average sun exposure of more than 4 hours (44%). Family history was observed in 18% cases. Malar type (68%) was the most common pattern observed. Mean MASI score was 5.7. WLE showed dermal type in 69% cases. Common findings on dermoscopy were reticular pigment network with perifollicular sparing and color varying from light to dark brown. Mean MELASQOL score was 28.28, with most patients reporting embarrassment and frustration. Conclusions: This study showed that melasma has a significant negative effect on QOL because though asymptomatic it is disfiguring affecting self-esteem. Dermoscopic examination did not help in differentiating the type of melasma.

Background : Melasma is a common acquired cause of facial hyperpigmentation with no definitive therapy. Tranexamic acid, a plasmin inhibitor, has demonstrated depigmenting properties and combining this oral drug with other modalities of treatment has shown promising results. Objectives : To compare the efficacy of a combination of oral tranexamic acid and fluocinolone-based triple combination cream with that of fluocinolone-based triple combination cream alone in melasma among Indian patients. Materials and Methods : 40 patients of melasma of either sex attending to dermatology OPD were enrolled in this study. Participants were randomly divided into two groups with 20 patients in each group. Group A patients were asked to apply the cream only and Group B patients received oral tranexamic acid 250 mg twice daily and applied a triple combination cream containing fluocinolone acetonide 0.01%, tretinoin 0.05%, and hydroquinone 2% once daily for 8 weeks. Response was evaluated using melasma area severity index (MASI) at baseline, 4 weeks, and 8 weeks. Results : 40 patients completed the study. The MASI scores at baseline, 4 weeks and 8 weeks in group A were 15.425 + 1.09, 11.075 + 9.167 and 6.995 + 6.056 respectively and in group B 18.243 + 1.05, 6.135 + 4.94 and 2.19 + 3.38. Intergroup comparison showed a faster reduction in pigmentation in Group B as compared to Group A and the results were statistically significant at 4 weeks (P value 0.014) and 8 weeks (P value 0.000). The efficacy was maintained throughout the 6-month follow-up period. Conclusion: Addition of oral tranexamic acid to fluocinolone-based triple combination cream results in a faster and sustained improvement in the treatment of melasma.

Background : Growth factors have long been known as an effective treatment for facial wrinkles. We developed growth factor concentrate (GFC) from the platelets and evaluated their clinical outcome in nasolabial folds. Aims and Objectives : We evaluated safety and efficacy of autologous GFC on patients with nasolabial folds. Materials and Methods : Study was conducted on 80 patients for nasolabial folds in two groups. Group I (20) received bilateral single injection of GFC and group II (60) received single injection of GFC on the right side of the face and platelet-rich plasma (PRP) on the left side of the face. Severity of nasolabial folds was determined at the baseline and 3 months of follow-up visits based on wrinkle severity rating scale (WSRS), Global aesthetic improvement scale (GAIS) and atlas photographic grading at rest and at full smile. Objective clinical assessment and subjective satisfaction scale was determined for overall improvement at the end of the study. Results : In group I, 2 subjects showed improvement after GFC treatment with the score of 3.1-4 (76-100%), 3 subjects with the score of 2.1-3 (51-75%), 14 with the score of 1.1-2 (26-50%) and 1 subject with the score of 0-1 (<25%) at the end of study. In group II, 51 subjects were evaluated at the end of study where, 34 (66%) showed superior improvements after GFC, 6 (11%) patients showed similar improvement on both side of the face, 10 (19.6%) patients showed no noticeable improvement on the either side of the face and only 1 patient (1.96%) showed superior improvement for PRP at the end of the study. Overall improvement score analysis showed that GFC was significantly superior to PRP (P < 0.001). Conclusion : Present study is a strong evidence to support the use of GFC for nasolabial folds. The results showed that the single application of GFC is highly effective and safe.

Context : Onset of vitiligo during childhood is not uncommon but the data is limited on this subject. Aims : This study was planned to assess the magnitude of childhood onset vitiligo (COV) and adulthood onset vitiligo (AOV), and compare their clinical pattern. Settings and Design : A cross sectional hospital based clinical study. Materials and Methods : Consecutive patients with vitiligo attending the Dermatology OPD of RNT Medical College and MB Government Hospital, Udaipur, from April 2012 to September 2012 were the subjects of this study. A detailed history taking followed by general, systemic and cutaneous examination, and relevant investigations were carried out. The findings were recorded in a proforma for analysis and interpretation of data. Statistical analysis used : Statistical analysis of data was done using chi- square and Z test. Results: Of the 295 patients seen during the study period, 109 (36.95%) were patients with COV while 186 (63.05%) had AOV; the COV: AOV ratio being 1: 1.71. Amongst COV patients, females (65/109; 59.63%) outnumbered males (44/109; 40.37%). Maximum (51; 46.79%) patients of COV had onset of their disease on head and neck, out of which eyelid was the initial site of lesion in 29 (26.61%) patients. None of COV patients had universal and isolated mucosal vitiligo. Conclusions : Female predominance, affection of eyelids as initial site, and less frequent mucosal involvement in COV were the clinical features different from AOV.

Alitretinoin is a pan retinoic acid agonist. It was initially used as 0.1% gel in the management of localized Kaposi's sarcoma. At present, the use of systemic alitretinoin has proved extremely efficacious in the management of recalcitrant chronic hand eczema. Furthermore, there have been other retinoid responsive dermatosis that have demonstrated remission post usage of systemic alitretinoin. With a better toxicity profile, compared to the other systemic retinoids, alitretinoin could be considered a valuable treatment option in the near future for the treatment of these dermatologic disorders.

Argyria is a condition characterized by pigmentary changes secondary to exposure to silver salts and its accumulation in skin, mucous membranes and annexes, which typically produces blue or gray-blue spots. A case of a male patient 62 years old, previously healthy, who has a blue-gray hyperpigmentation on the face, trunk and upper extremity, affecting sun-exposed areas is presented. He admitted having ingested silver nitrate for 5 years at a rate of 1 bottle per week, with the intent to kill microorganisms in his body.

Congenital rubella syndrome involves a configuration of systemic and cutaneous manifestations in a neonate due to in utero infection caused by the rubella virus. The case of a preterm neonate with blueberry muffin lesions and classical as well as rare systemic features of congenital rubella syndrome is reported.

Angioleiomyomas are benign tumors originating in the vascular smooth muscle. The tumor typically presents as painful, solitary, small (<2 cm), slow growing, subcutaneous nodule. Angioleiomyoma of the knee is rare, and only few cases have been reported so far. We have described herein a giant angioleiomyoma of the knee presenting as a painless ulcer in a 22-year-old man. There was no intra-articular extension of the tumor, and total excision was curative. This is the first case report of giant angioleiomyoma of the knee as well as the first case report of angioleiomyoma presenting as a painless ulcerative lesion.

Eosinophilic pustular folliculitis (EPF) was originally described by Ofuji in Japanese patients without any systemic disease. Later it was widely associated with HIV. Lately a large number of hematological malignancies have been associated with EPF. We hereby report an association of non-Hogkins lymphoma with EPF, probably the first in Indian context.

We report a 79-year-old Japanese man who developed subepidermal blistering skin disease after an 8-year history of psoriasis. Histology of a bullous lesion revealed a subepidermal blister with a mixed inflammatory cell infiltrate and fibrin nets. Indirect immunofluorescence using normal human skin sections revealed IgG and IgA autoantibodies in the patient serum, which bound to the epidermal side of 1M NaCl-split skin sections. Immunoblot analysis revealed that both IgA and IgG antibodies reacted with the BP180 NC16a domain and the 120-kDa LAD-1 and that IgG antibodies also reacted with the BP180 C-terminal domain and laminin gamma-1. These findings indicated that autoantibodies to laminin gamma-1 and multiple epitopes in BP180 ectodomain played a role in the pathogenesis of this unique autoimmune subepidermal blistering skin disease associated with psoriasis.

Cutis laxa is a heterogeneous group of diseases, with loose, wrinkled skin folds and hyperelasticity of the skin. There are overlapping of clinical features of the group of syndrome associated with cutis laxa, including congenital cutis laxa, wrinkly skin syndrome and gerodermia osteodysplastica. All these conditions present a challenge to the clinician. Thus, molecular diagnosis is the only way to resolve these phenotypically similar conditions. We hereby describe two Indian patients with wrinkled skin and mild craniofacial dysmorphic features who had molecular confirmation of autosomal recessive cutis laxa.

Cutaneous larva migrans or creeping eruptions is a cutaneous dermatosis caused by hookworm larvae, Ancylostoma braziliense. A 2-month-old female child presented with a progressive rash over the left buttock of 4 days duration. Cutaneous examination showed an urticarial papule progressing to erythematous, tortuous, thread-like tract extending a few centimeters from papule over the left gluteal region. A clinical diagnosis of cutaneous larva migrans was considered. Treatment with albendazole led to complete resolution, confirming the diagnosis. This is to the best of our knowledge, the youngest age at which this condition is being reported.

Cutaneous pseudolymphomas are benign lymphoproliferative processes mimicking lymphomas clinically and histologically. One of the precipitating factors for pseudolymphoma is drugs like anticonvulsants, antidepressants and angiotensin-converting enzyme inhibitors. According to existing literature phenytoin-induced cutaneous pseudolymphomas are usually T-cell predominant. Most often withdrawal of the drug with or without short-course systemic steroids can attain a cure. Rarely malignant transformation has been reported years later despite withdrawal of the offending drug, which necessitates a long-term follow up of the affected. We report an 80-year-old male patient who was receiving phenytoin sodium and who presented with diffuse erythema and infiltrated skin lesions which histologically resembled cutaneous B-cell lymphoma. Substituting phenytoin with levetiracetam achieved resolution of symptoms. Further evaluation was suggestive of a reactive process. A detailed drug history is of paramount importance in differentiating drug-induced pseudolymphoma from lymphoma. Searching literature we could not find any previous reports of phenytoin-induced cutaneous B-cell pseudolymphoma.

Ichthyosis hystrix is a rare autosomal dominant genodermatosis, characterized by persistent spiny hyperkeratotic scales which cover a significant part of the skin surface. Based on the pattern of distribution, five clinical variants namely Brocq type, Lambert type, Curth-Macklin type, Rheydt type and Bδfverstedt type have been described. We report the case of an 11-year-old male child with spiny, hyperkeratotic scales all over the body since birth with sparing of scalp and central part of the face. Palmoplantar keratoderma was also present. These clinical features are suggestive of Ichthyosis Curth Macklin, which has been typically described in families. However, family history was negative in our patient. The case is being reported on account of rarity of the disease, that too with a very rare sporadic presentation.

Subcutaneous or deep granuloma annulare is a benign asymptomatic condition characterized by firm asymptomatic nodules in deep subcutaneous tissues that may be associated with intradermal lesions. A 53-year-old female presented with asymptomatic skin-colored, firm nodules over the right ring finger. Histopathology revealed a palisading granuloma with central degenerated collagen and mucin deposition in the dermis suggestive of granuloma annulare. Isolated and unilateral involvement of a single digit with clusters of nodules of subcutaneous granuloma annulare (GA) in an adult is rare and differentiation from its simulator rheumatoid nodule is essential.

Cutaneous metastasis in a zosteriform pattern is a very rare entity being reported only in 63 patients worldwide. Cutaneous metastases usually presents late in the course of the disease or sometimes after the treatment of the primary when it indicates recurrence of a treated malignancy. We report a case of zosteriform cutaneous metastases masquerading as lymphangioma without prior presentation of the primary malignancy.

Becker's nevus is a focal epidermal hypermelanotic disorder. It morphologically presents as unilateral, hyperpigmented, hypertrichotic patch on upper trunk, proximal upper extremities and arms. However, Becker's nevus presenting as bilateral, symmetrical patches is rare. Herein, we report a rare case of giant Becker's nevus with bilateral symmetrical presentation in an adult male.

Giant onychomatricoma is a rare fibroepithelial nail matrix tumor with only two previous reports in literature, from Mexico. An 80-year-old female patient presented with a progressively painless mass in the left great toe nail, following trauma, of 2 years duration. On examination there was a single, hard, immobile mass of size 4 × 3 × 2 cm with proximal hyperpigmentation of the left great toe nail. The mass was totally excised and a punch biopsy of nail matrix was taken. Histopathology revealed hyperkeratosis, acanthosis, multiple channels lined by flattened epithelium and fibrocollagenous tissue in horizontal orientation in deeper layers. The patient had no recurrence after 1 month. We report this case for its rare and distinct clinical presentation, characteristic histopathology and easy surgical treatment.

Neurofibromatosis type 1 (NF1) represents a major risk factor for development of malignancies, particularly malignant peripheral nerve sheath tumors (MPNST), optic gliomas, other gliomas, and leukemia. We report an unusual case of chronic myeloid leukemia (CML), developed in a patient of NF1. A 40-year-old Indian male, clinically manifesting NF1 since his childhood, presented with huge splenomegaly. Patient also had a large tumor mass arising in a café-au-lait spot on lower back with rapid growth in last 6 months. Excision of this tumor was done, and it turned out to be a diffuse neurofibroma histologically. Peripheral smear was also done in view of splenomegaly, which showed features of chronic myeloid leukemia. CML rarely co-exists with NF1, and there are a very few reports of such cases. It is important to be aware of the possibility that not only the malignant change in benign PNST is more common in these patients, but also other malignancies like CNS tumors and hematolymphoid neoplasm do occur with increased frequency.

Bacillary angiomatosis is an infectious disease caused by two Gram-negative bacilli; this disease usually affects immunosuppressed hosts with a history of cat scratch. We report a rare case of bacillary angiomatosis in an immunocompetent 26-year-old woman with no history of exposure to cats, and with atypical clinical features (very pruritic vascular papules and nodules with ulceration and hemorrhage on the right arm and fingers). She was successfully treated with clarithromycin for 3 months. Bacillary angiomatosis must be kept in mind in the differential diagnosis of any papules and nodules in cases of unknown etiology and also in immunocompetent patients and HIV-negative individual.

Epidemic Kaposi sarcoma is a common finding among HIV/AIDS patients that are not under antiretroviral treatment, and sometimes it is the first sign of the disease. However, it can be seen even in patients with undetectable viral load and high CD 4 cell count. Under these circumstances, the clinical presentation can be atypical in location or number. For this reason, the number of differential diagnosis is increased and biopsy of the suspicious lesions is essential for an accurate diagnosis and further apropiate treatment.

Eccrine poromas are benign, slow-growing, solitary tumors originating from the intraepidermal portion of eccrine sweat ducts. Approximately 65% of these tumors occur on the soles of the feet, while 10% occur on the hands where a high concentration of eccrine sweat glands exists. Less frequently it occurs in other sites such as neck, chest, forehead, nose, and scalp with sporadic occurrences. A 43-year-old Korean female presented with a mass on her right auricle, which had been present for 5 years. The mass increased gradually in size with pain, oozing, and bleeding. A biopsy of the mass revealed monomorphic basaloid cells, which may extend into the underlying dermis, in a richly vascularized stroma, with a variable number of cystic or ductal structures. The patient was diagnosed as having eccrine poroma. In this case, the eccrine poroma showed unusual clinical presentation.

Imatinib, a tyrosine kinase inhibitor, is well known to cause hypopigmentation because of its inhibitory effect on melanocytes. Herewith we report a case of chronic myeloid leukemia who developed extensive hyperpigmentation following imatinib therapy.

Coexistence of two different histopathological types of basal cell carcinomas (BCCs) in the same anatomical site is rare and interesting. Herein, we report a case of coexistence of nodular and adenoid BCC in a 78-year-old peasant who presented with a plaque and a globular swelling on left paranasal region of few years duration. Histopathology of skin biopsy with immunohistochemistry study using antibodies to S100, epithelial membrane antigen (EMA) and cytokeratin 7 (CK 7) from the margin of the ulcer and globular swelling confirmed the diagnosis that revealed features of nodular and adenoid basal cell carcinoma, respectively. Investigative work up did not reveal evidence of metastasis.

Mal de meleda (MdM), a rare autosomal recessive genodermatosis is characterized by erythema and hyperkeratosis of the palms and soles with a sharp demarcation and that progress with age (progrediens) and extend to the dorsal aspects of the hands and feet (transgrediens). It has been associated with various conditions albeit rarely with congenial cataract. Ocular lens and the skin have the same embryological origins. We hereby present this novel case report of Mal de meleda in association with congenital posterior subcapsular cataract which to the best of our knowledge has not been reported from India before.

A 30-year-old male presented to the dermatology department with complaints of multiple ulcers over both legs of 6 years duration. The ulcers had a waxing and waning course with present exacerbation of lesions since 1 month. Dermatological examination revealed multiple ulcers distributed in a reticular pattern over medial and lateral aspects of both lower legs, extensor aspect of both ankles and dorsum of both feet. Multiple interspersed atrophic porcelain white scars were also present. Investigations revealed raised serum homocysteine levels. A skin biopsy from the ulcers showed features of livedoid vasculopathy. Following recurrence of lesions after oral corticosteroid therapy, the patient was given a course of hyperbaric oxygen therapy for the ulcers to which he responded very well. This case is being presented for the novel option of hyperbaric oxygen therapy in livedoid vasculopathy, which by itself is rarely reported in this part of the world.

Woolly hair is a hair shaft disorder characterized by fine and tightly curled hair. Woolly hair could be syndromic (associated with systemic disease) or non-syndromic (not associated with any systemic disease). Woolly hair is described in association with many skin, dental, ophthalmic and cardiac anomalies but association of woolly hair with bilateral systematized epidermal nevus described in our case is first of its kind.

Chediak-Higashi syndrome (CHS) is a rare autosomal recessive disease, characterized by partial oculocutaneous albinism, frequent pyogenic infections, and the presence of abnormal large granules in leukocytes and other granulecontaining cells. The abnormal granules are readily seen in blood and marrow granulocytes. Other clinical features include silvery hair, photophobia, nystagmus and hepatosplenomegaly. However, the presence of abnormal giant intracytoplasmic granules in neutrophils and their precursors are diagnostic of CHS. Here, we present a series of five cases, out of which four presented in the accelerated phase. In all the five cases, the giant granules were noted predominantly in the cytoplasm of lymphocytes, which is a rare occurrence compared to those present in the granulocytes.

Pachyonychia congenita (PC) is a rare autosomal dominant genodermatosis characterized by hyperkeratosis affecting the nails and palmoplantar areas, oral leucokeratosis, and cystic lesions. It is classically subdivided into two major variants, PC-1 (Jadassohn-Lewandowski syndrome) and PC-2 (Jackson-Lawler syndrome), according to the localization of the mutations in the KRT6A/KRT16 or KRT6B/KRT17 genes, respectively. We report a 9-year-old male patient with a history of thickened, discolored nails, raised spiny skin lesions all over the body since birth with focal plantar keratoderma and absence of natal teeth.

Histoid leprosy is an uncommon entity with specific clinical, histopathological and bacteriological features. Histoid lepromas are sudden eruption of dome shaped lesions usually associated with dapsone resistance, as a variant of lepromatous leprosy or rarely arising de novo. We report a case who presented for the first time with histoid features with no history of taking dapsone/antileprosy treatment earlier in an elderly male with small to large lesions over normal skin in the post-leprosy elimination era.

Chronic graft versus host disease (GVHD) is a less frequently seen disease that occurs post solid organ or bone marrow transplantation. Chronic GVHD occurring post blood transfusion is an even more uncommon disease. It can present either as a lichenoid disease or as a sclerodermatous disease involving multiple systems. In this article, we report a case of chronic graft versus host reaction occurring in skin secondary to blood transfusion.

Vulval swellings have always caused dilemmas in diagnosis and more so when they are huge in size. Sebaceous cysts are known to occur as a result of blocked pilo-sebaceous gland and duct or as a result of any injury to the skin. Face, neck, chest, back, scalp, and ears are known sites, however, they also occur over private parts. They are mostly asymptomatic but cause intense pain and discomfort if infected. Symptomatic cysts warrant removal.

Background: Prurigo nodularis is a dermatological manifestation secondary to chronic scratching or picking on focal areas of the skin. Its pathogenesis remains poorly understood, and limited data has indicated its association with psychological factors. Aim: To determine the biological, psychological and social factors associated with the occurrence of prurigo nodularis in patients with underlying endogenous eczema. Methods: A prospective case-control questionnaire -based study on patients with endogenous eczema, with and without prurigo nodules, was performed. The Impact of Skin Disease on Daily Life questionnaire was used to assess dimensions of physical functioning, including extent and severity of skin disease, itch, pain, fatigue and scratching, as well as dimensions of psychological and social functioning, including mood, illness cognition, disease-related impact, stigmatization and social support. Results: Thirty-six cases and 47 controls were recruited. Patients with endogenous eczema and prurigo nodules indicated a higher itch score on the visual analog scale over the previous 4 weeks compared to those without prurigo nodules (p=0.0292). There were no significant differences between the 2 groups in the scores reflecting the other parameters of physical, psychological and social functioning. Conclusion: In patients with endogenous eczema, those with prurigo nodules experience a greater itch intensity compared to those without prurigo nodules. There were no other physical, psychological and social factors that were found to be associated with the occurrence of prurigo nodules in endogenous eczema.

Background: Erythema dyschromicum perstans, a rare dermatosis of obscure etiopathogenesis and significant cosmetic morbidity, have no satisfactory treatment. Observations: Two patients with having characteristic asymptomatic and slowly progressive, slate-grey macular lesions with distinct red borders involving the face, neck, upper trunk and limbs were diagnosed clinicopathologically as erythema dyschromicum perstans. Both were treated successfully with topical tacrolimus 0.1% ointment. Conclusions: Overall, response to several therapeutic modalities including clofazimine and dapsone therapy is said to vary from complete failure to variable or inconsistent. Topical tarolimus provides an effective and safe alternative therapeutic option in erythema dyschromicum perstans.

Magnetic resonance imaging (MRI) has established itself as diagnostic modality of choice of soft tissue and musculoskeletal lesions but dermatological lesions have been diagnosed mainly by clinical examination. We present MRI features of dermal and subcutaneous verrucous hemangioma involving the dorsum of foot in a 20-year-old male and its usefulness in differentiating it from angiokeratoma with similar clinical features.
