Lyme disease is a multisystem illness which is caused by the strains of spirochete Borrelia burgdorferi sensu lato and transmitted by the tick, Ixodes. Though very commonly reported from the temperate regions of the world, the incidence has increased worldwide due to increasing travel and changing habitats of the vector. Few cases have been reported from the Indian subcontinent too. Skin manifestations are the earliest to occur, and diagnosing these lesions followed by appropriate treatment, can prevent complications of the disease, which are mainly neurological. The three main dermatological manifestations are erythema chronicum migrans, borrelial lymphocytoma and acrodermatitis chronica atrophicans. Many other dermatological conditions including morphea, lichen sclerosus and lately B cell lymphoma, have been attributed to the disease. Immunofluorescence and polymerase reaction tests have been developed to overcome the problems for diagnosis. Culture methods are also used for diagnosis. Treatment with Doxycycline is the mainstay of management, though prevention is of utmost importance. Vaccines against the condition are still not very successful. Hence, the importance of recognising the cutaneous manifestations early, to prevent systemic complications which can occur if left untreated, can be understood. This review highlights the cutaneous manifestations of Lyme borreliosis and its management.

Background: The p53 gene is a critical molecular in the protection of cells from DNA damage due to Ultraviolet (UV) exposure, and TP53 mutation is very common in non-melanoma skin cancer. Objectives: To assess the association between the TP53 Arg72Pro polymorphism and non-melanoma skin cancer (NMSC) risk. Methods: We performed this meta-analysis with 13 case-control studies involving 3,520 cases and 3,587 controls. Results: Our meta-analysis showed that TP53 Arg72Pro polymorphism was not associated with non-melanoma skin cancer susceptibility in overall population.(for Arg/Arg vs. Pro/Pro: OR 0.98, 95% CI 0.80-1.19; for Arg/Pro vs. Pro/Pro: OR 0.99, 95% CI 0.84-1.17; for the recessive model Arg/Arg vs. Arg/Pro + Pro/Pro: OR 1.10, 95% CI 0.89-1.35; for the dominant model Arg/Arg + Arg/Pro vs. Pro/Pro: OR 1.00, 95% CI 0.85-1.18). We also detected no effect of this polymorphism on any subtype of non-melanoma skin cancer, such as squamous cell carcinoma (SCC), and basal cell carcinoma (BCC). Furthermore, no significant association in any subgroup was detected in stratified analyses according to ethnicity. However, in the stratified analysis by sample collection resources, Arg/Arg carriers from tumor tissue subgroup had 3.42 times risk of cancer (95% CI, 1.19 to 9.84) as compared with the variant type Pro/Pro in NMSC. Conclusions: TP53 Arg72Pro polymorphism may have little involvement in the pathogenesis of NMSC, regardless of type, including SCC, and BCC.

Background and Aims: The cellular mechanisms responsible for initiating or limiting the tumors including skin types are of great importance. The p53 is a tumor-inhibiting gene which is believed to be defective in many malignant situations. Ki67 is a non-histonic protein which is mainly interfere with the proliferation and has many controlling effects during the cell cycle. Because of their importance in skin tumor cell growth, this study aimed at evaluating the p53 and Ki67 expression in skin epithelial tumors by immunohistochemical method. Materials and Methods: In a descriptive setting, 50 biopsy samples (30 basal cell carcinomas (BCCs), 10 squamous cell carcinomas (SCCs), 8 keratoacanthomas (KAs), and 2 trichoepitheliomas (TEs)) were immunohistochemically evaluated for p53 and Ki67 expression during a 14-month period. The incidence and expression rate of these two variables were separately reported in each group of samples. Results: The expression rate of p53 was 67.77% for the BCCs, 50.20% for the SCCs, and null for the KAs. For both TEs, it was 50%. The expression rate of Ki67 was 57.33% for the BCCs, 47.70% for the SCCs, 37.5% for the KAs, and 0.0% for TEs. The incidence of P53+ cells was 100% and 90% in the BCC and SCC samples, respectively. The both TEs were positive in this regard. The incidence of Ki67+ cells was 100% for the BCC, SCC, and KA samples. The both TEs were negative in this regard. Conclusion: This study showed that the incidence rate of p53- and Ki67-positive cells is very high in skin malignant epithelial tumors. The expression rate of these two variables is comparable with reports in the literature. Further studies with large sample size are recommended to be carried out for KA and TE samples.

Background: Kangri cancer is peculiar to the valley of Kashmir as people of all age groups are accustomed to warm their bodies by the use of Kangri baskets.The clinical spectrum of skin cancer in the Kashmir valley is entirely different from the rest of the country, which could be attributed to the use of Kangri in this geographical region. ^[1],[2] Aims: Histopathological analysis of the cutaneous changes due to kangri use in Kashmiri population. Materials and Methods: This is a prospective hospital based study. All the patients attending the outpatient department of Dermatology, STD and Leprosy at SMHS Hospital, an associated hospital of govt. medical college in Srinagar and presented with suspicious lesions (i.e., erythema ab igne, papular or nodular skin growths) due to Kangri use were taken up for the study. A detailed history including the use of Kangri and a physical examination was done in each patient followed by a histopathological examination in case of suspicious lesions. Results: The cutaneous changes which were observed during the study period of 8 months were erythema ab igne, bowen's disease and squamous cell carcinoma. Conclusion: Although this is a preliminary study we will be studying more of such changes caused due to Kangri use in the future.

Toxic epidermal necrolysis is the life-threatening dermatological emergency, most often an adverse cutaneous drug reaction with high mortality. A 6-month prospective study was conducted in our institution to find out the offending drugs, to assess the prognosis on admission using SCORTEN: Severity of illness score and to find out the treatment outcome. Anticonvulsants, NSAIDs and sulphonamides are the common offending agents; but in our study, 2 were due to homeopathic medicines. Out of 20 patients, on the date of admission SCORTEN prognostic score was 2 in 11 patients, 3 in 8 patients and 4 in 1 patient. Eighteen patients were treated with dexamethasone intramuscular injection and 2 patients got intravenous immunoglobulin (IVIG). All patients survived without any mortality. Though improvement was slightly faster with IVIG, early administration of corticosteroids was also of encouraging efficacy and should be considered in developing countries due to low cost. No mortality in our study suggests need to validate the SCORTEN index in our country in a large number of patients.

Photography has proven to be a valuable tool in the field of dermatology. The major reason for poor photographs is the inability to produce comparable images in the subsequent follow ups. Combining digital photography with image processing software analysis brings consistency in tracking serial images. Digital photographs were taken with the aid of an instrument which we designed in our workshop to ensure that photographs were taken with identical patient positioning, camera angles and distance. It is of paramount importance in aesthetic dermatology to appreciate even subtle changes after each treatment session which can be achieved by taking consistent digital images.

Granuloma annulare (GA) is a disease characterized by granulomatous inflammation of the dermis. A variant form of the disease, generalized granuloma annulare (GGA), can be observed in 15% of affected patients. Localized GA is likely to resolve spontaneously within months or a few years, whereas GGA can persist for decades. There are various therapies for treating GGA. Monthly combination therapy of rifampicin 600 mg, ofloxacin 400 mg, and minocycline 100 mg (ROM) is used for treating paucibacillary leprosy which shares both clinical and histopathologic similarities with GA. Therefore, we decided to evaluate the possible efficacy of monthly ROM in a patient with GGA.

Background: Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation. Aims: To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model. Materials and Methods: One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation. Results: A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined. Conclusion: The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described.

Classification is based on GA ² LEN/EAACI/WAO/EDF guidelines (2009). These guidelines classify urticaria according to clinical manifestations. Urticaria is mediated by mast cells. According to level of mast cell degranulation clinical signs are superficial (Urticaria) or deep swelling (Angioedema).

Acute urticaria do not need extensive diagnostic procedures. Urticaria activity score is a useful tool for evaluation of urticaria. Complete blood count, Erythrocyte sedimentation rate and C reactive protein are important investigations for diagnosis of infections in urticaria. Autologous serum skin test is a simple office procedure for diagnosis of auto reactive urticaria. Closed ball point pen tip is a simple test to diagnose dermographism.

H _1- antihistamines, the mainstay of treatment for urticaria, were developed from anticholinergic drugs more than 70 years ago. They act as inverse agonists rather than antagonists of histamine H ₁ -receptors which are members of the G-protein family. The older first generation H _1- antihistamines penetrate readily into the brain to cause sedation, drowsiness, fatigue and impaired concentration and memory causing detrimental effects on learning and examination performance in children and on impairment of the ability of adults to work and drive. Their use should be discouraged. The newer second-generation H ₁ -antihistamines are safer, cause less sedation and are more efficacious. Three drugs widely used for symptomatic relief in urticaria, desloratadine, levocetirizine and fexofenadine are highlighted in this review. Of these levocetirizine and fexofenadine are the most potent in humans in vivo. However, levocetirizine may cause somnolence in susceptible individuals, whereas fexofenadine has a relatively short duration of action and may be required to be given twice daily for all round daily protection. Although desloratadine is less potent, it has the advantages of rarely causing somnolence and having a long duration of action.

Autologous serum therapy is a promising therapy for treatment resistant urticaria. This is useful in developing countries as this is economical option. Minimum instruments like centrifuge, syringe and needles are required for the procedure.

Three cases with single lesion of Alopecia mucinosa (follicular mucinosis) were treated with antileprosy treatment and showed rapid and complete resolution of the lesions with no recurrence on extended follow-up. Two children, a boy aged 14 years and a girl aged 12 years presented themselves, each, with a single hypopigmented, hypoesthetic patch on the face. Clinically leprosy was suspected, however, skin biopsy from both patients revealed follicular mucinosis as the only pathological finding, without any granulomas. Based on clinical suspicion both were started on multi drug therapy (MDT) for leprosy with complete resolution of the lesions. The third case, male, aged 22 years presented with a single erythematous, hypoesthetic plaque on the forehead.This lesion had been diagnosed as follicular mucinosis with folliculo-tropic mycosis fungoides, in the USA. He too responded completely within 3 months with rifampicin, ofloxacin, minocycline (ROM) treatment, which was given once monthly for a total of 6 months and remains free of disease since the past 1 year. Follicular mucinosis as the only pathology may be seen in facial lesions of clinically suspected leprosy in children and young adults. Based on histological findings these cannot be diagnosed as leprosy and will be considered as Alopecia mucinosa. These lesions, however, are always single and show rapid and complete response to antileprosy treatment. The authors suggest that in regions endemic for leprosy, such as India, single lesion Alopecia mucinosa on the face in children and young adults should be given antileprosy treatment.

Encephalocraniocutaneous lipomatosis (ECCL) is a rare sporadic neurocutaneous syndrome characterized by presence of central nervous system, ocular and cutaneous anomalies. The exact pathogenesis is still not known. We present the third case from the Indian subcontinent, who is a five year old girl with history of right sided seizures. Dermatological examination showed alopecia on right side of the scalp and ipsilateral limbal dermoid and nodular skin tags over the upper eyelid. The computerized tomography scan of the brain revealed porencephalic cyst, cerebral calcifications and atrophy of right brain. The histopathology of the skin lesions showed lipomatous hamartoma and features of non scarring alopecia. The constellation of these findings and in adherence to the diagnostic criteria of ECCL proposed in 2009, we consider this report as a definite case of ECCL.

Introduction: Cutaneous leishmaniasis (CL) is a parasitic disease which has different clinical forms. The aim of this study is to compare the response to leishmanin skin test (LST) in three forms of CL including plaque type, lupoid type, and sporotrichoid type. Materials and Methods: This was a descriptive cross-sectional study. The patients enrolled in this study had three clinical forms of CL confirmed by positive smear of their lesions and then LST was performed for them. Results were categorized as negative (0-5 mm induration), positive (6-14 mm), and strongly positive (≥15 mm). The data were documented in the patients' files and analyzed with SPSS windows software version 16 (Inc.Chicago, USA). Results: 200 patients were enrolled in the study. In the group with plaque type, 86% had a positive LST, 13.3% were negative, and 0.7% were strongly positive. In the lupoid group, these figures were 45.8%, 8.4%, 45.8%, respectively. In the sporotrichoid group, LST was positive in 27.3%, negative in 72.7%, and none of the patients had a strongly positive reaction ( P < 0.05). Discussion: The most of the positive LST were belong to plaque and lupoid groups, the most of strongly positive were belong to lupoid, and the most of negative LST were related with sporotrichoid type. Conclusion: It can be suggested that lupoid and sporotrichoid types of CL are parts of a continuous spectrum of the disease with an enhanced cellular immunity in lupoid form and a decreased state in sporotrichoid type.

Aim: To evaluate with SCORAD system the contribution of the diagnostic hypoallergenic diet on the severity of atopic dermatitis and especially on the the intensity criteria and subjective parametersin patients over 14 years of age. Materials and Methods: The diagnostichypoallergenic diet was recommended for the period of 3 weeks. Severity of eczema was scored in agreement with SCORAD score, and especially the intensity criteria (erythema, edema, crusting, excoriations, lichenifications, dryness) and subjective parameters (pruritus, sleeplessness) were evaluated at the beginning and at the end of this diet. Results: One hundred and forty-eight patients suffering from atopic dermatitis were included in the study: 107 women and 41 men with the average age of 26.03 (s.d. 9.6 years), min. 14 max. 63 years. In the end of 3 weeks diagnostic hypoallergenic diet there was a statistically significant reduction in severity of sleepless and pruritus and in all of the intensity criteria except of lichenification. Conclusion: The diagnostic hypoallergenic diet can improve the intensity criteria and subjective parameters of atopic dermatitis evaluated in SCORAD, but not the lichenification. We recommend to introduce this diet before a challenge tests and as a temporary medical arrangement in patients suffering from moderate or severe form of atopic dermatitis.

Background: Vascular endothelial dysfunction is a central event in pathogenesis of a variety of human diseases. Systemic sclerosis is one of such diseases.The oxidative stress and depletion of antioxidants in the serum is believed to be one of the factors in causing this dysfunction. Aims: The aim of this case control study was to compare the levels of antioxidants in the serum of patients with systemic sclerosis and the normal age and sex matched controls. Materials and Methods: Our study consisted of 16 successively admitted patients with systemic sclerosis and 16 healthy, age and sex matched controls. The age group of patient's ranged between 25 and 55 years. The duration of the disease in patients ranged from 1 to 8 years. The serum of patients and controls were assayed for the levels of antioxidants (GSH, NO, MDA, SOD and GPX) by spectrophotometry. The statistical method of analysis used was the one sample t-test. Results: The median levels of antioxidants in the control patients were: SOD-4.14 units/ml; GSH-4.76 units/ml; NO-5.58 nmol/l; MDA-0.53 nmol/l and GPX-49 μmol/l. The levels of NO, GSH and SOD were decreased in these patients with a significant P value (<0.001) whereas the levels of GPX and MDA were normal to increased with a significant P value. Conclusion: The depletion of antioxidants and oxidative stress in serum might be responsible for the vascular dysfunction and other hallmark manifestations of systemic sclerosis. Therefore micronutrient antioxidant supplements may be of therapeutic value.

Background: Malassezia is a lipid-dependent yeast known to cause Pityriasis versicolor, a chronic, recurrent superficial infection of skin and present as hypopigmented or hyperpigmented lesions on areas of skin. If not diagnosed and treated, it may lead to disfigurement of the areas involved and also result in deep invasive infections. Aim: The aim of the present study was to identify and speciate Malassezia in patients clinically suspected of having Pityriasis versicolor. Materials and Methods: Total 139 patients suspected of having Pityriasis versicolor were evaluated clinically and diagnosis was done by Wood's lamp examination, confirmed mycologically by using KOH, cultivation on Sabouraud's dextrose agar and modified Dixon agar at a tertiary care hospital in Mumbai. The total duration of study was 12 months. Results: Majority of the patients were males (59.71%) in the age group of 21-30 years (33.81%) who were students (30.21%) by profession. The incidence of Malassezia in Pityriasis versicolor was 50.35%. The most common isolate was M. globosa (48.57%), followed by M. furfur (34.28%). Majority of the patients had hypopigmented lesions, with M. globosa as the predominant isolate. Neck was the most common site affected; 88.48% were Wood's lamp positive of which 56.91% of Malassezia isolates grew on culture. KOH mount was positive in 82.01% of which 61.40% Malassezia isolates grew on culture. Conclusions: The procedure of culture and antifungal testing is required to be performed as different species of Malassezia are involved in Pityriasis versicolor and susceptibility is different among different species. Thus, it would help to prevent recurrences and any systemic complications.

Background: Melasma is a common acquired facial hypermelanosis. Conventional treatment of melasma includes a sunscreen and hypopigmenting agents. The treatment of this recalcitrant disorder is often difficult and unsatisfactory. Aims: The objective is to carry out a detailed clinical study of melasma and to assess the therapeutic effect and side effects of certain currently available topical modalities for the treatment of melasma. Materials and Methods: 160 patients of all age groups and both sexes were treated sequentially with five different combination regimes for 3 months. Assessment of the response was done subjectively as well as by melasma area and severity index (MASI). Results: Out of the five modalities studied, the modified Kligman's formula was the most effective. However, it had comparatively higher incidence of side effects. Conclusions: Among the currently available topical modalities for the treatment of melasma, the most effective combination is the modified Kligman's formula. However, in view of the side effects it causes, it must be used with caution and proper counseling.

Background:The etiology of skin tags (STs) is not fully understood. A relation to diabetes mellitus and obesity was suggested. Few studies of possible mast cells (MCs) involvement were reported. Tyrptase is a mast cell mediator and a potent fibroblast growth factor. It may provide a molecular link between mast cell activation and fibrosis. Aims: The aim was to assess clinical and laboratory findings in patients with STs, and the possible link between obesity, dyslipidemia, and lesional MC count/tryptase expression. Materials and Methods: A total of 20 patients with STs were subjected to clinical examination, estimation of body mass index (BMI), fasting blood glucose (FBG), postprandial blood glucose (PPBG), serum cholesterol and triglycerides, abdominal ultrasound for fatty liver assessment, in addition to study of MCs through staining for MC tryptase in two skin biopsies; lesional and nonlesional (control). Results:All patients showed abnormally high BMI and hypertriglyceridemia, with abnormal sonographic pattern in 15 patients (75%). STs number positively correlated with the age of patients. STs showed significantly higher MC counts and tryptase expression, compared with control skin ( P < 0.001), with no correlation of the STs number or MC count with BMI, FBG, PPBG or serum cholesterol. Obese patients showed a significantly higher MC count than overweight and there was a positive correlation between MC count and serum triglycerides. Axilla and under breast STs showed a higher MC count compared with other sites. Conclusions:STs seem to be related to obesity and hypertriglyceridemia. MCs with their tryptase are possibly involved in pathogenesis of STs. MC count is related to the associated factors; obesity and serum triglycerides. MC tryptase expression is a reliable method for accurate tissue MC counting.

Introduction: One of the most important complications after burning is hypo/depigmentation. This study was designed to compare two methods of cell spray and intradermal injection of epidermal cell suspension for treatment of burn induced hypopigmentation. Material and Methods: In this study, 28 patients with post burn hypo/depigmentation were selected and divided in 2 groups. A small skin biopsy was taken from normal skin of patients in operation room and epidermal cell suspension was prepared using NaBr 4N and trypsin. In the first group, the epidermal cell suspension was sprayed on the wound surface and then the area was dressed with amniotic membrane and gauze. In the second group, the cell suspension was injected in intradermal manner in the hypopigmented area. The patients were followed up and to evaluate the effect of the cells, photos were taken from the area before operation and also at follow-up. Clinical evaluation was done by the surgeon and a clinical score between "0" to "4" was used to demonstrate the clinical status from poor to excellent pigmentation. Skin biopsies were taken from depigmented area before and after interventions. Melanocytes were stained using anti S100 antibody and were counted in ×400 magnification fields. Results: Eighteen patients were in cell spray and 10 were in cell injection groups. Mean change of pigmentation in two group showed that there was no statistical significant differences in pigmentation between two groups, (P value = 0.52) although a limited improvement in pigmentation status was observed in both groups. Regarding melanocyte numbers per field, there was not a significant difference between two groups and also before and after interventions, but melanocyte number increased after treatment in both groups. Conclusion: We did not find noticeable differences between cell spray and intradermal injection methods. Although both methods showed a limited effect on pigmentation of depigmented skin, the clinical results were not satisfactorily for both patients and clinicians.

In traditional follicular unit extraction technique, 0.8-1.4 mm punch is used to cut the dermis to the level of attachment of erector pili muscle, so that the intact follicular unit grafts can be extracted. However, the larger extraction sites and higher hair root transection rates are some difficulties encountered while using the punch to extract body hair grafts. To overcome these difficulties, expanding needle concept has been devised. It approaches the extraction process by customizing the extraction wound to the architecture of the follicular unit and by performing most of the dissection of the dermal attachments to the donor follicular unit under direct magnified vision.

Nickel is a ubiquitous trace element and the commonest cause of metal allergy among the people. Nickel allergy is a chronic, recurring problem; females are affected more commonly than males. Nickel allergy may develop at any age. Once developed, it tends to persist life-long. Nickel is present in most of the dietary items and food is considered to be a major source of nickel exposure for the general population. Nickel in the diet of a nickel-sensitive person can provoke dermatitis. Careful selection of food with relatively low nickel concentration can bring a reduction in the total dietary intake of nickel per day. This can influence the outcome of the disease and can benefit the nickel sensitive patient.

Psoriatic arthritis (PsA) is increasingly being recognized to cause progressive joint damage and disability. PsA unresponsive to non-steroidal anti-inflammatory drugs (NSAIDs), the conventional first-line choice of treatment, is usually managed with disease-modifying antirheumatic drugs (DMARDs) especially methotrexate. An 18-year-old HIV-negative male had progressively severe PsA of 4-month duration that was nearly confining him to a wheel chair. He did not respond to multiple NSAIDs, alone or in combination with methotrexate (15 mg/week), given for 4 weeks. Addition of prednisolone (10 mg on alternate days) controlled his symptoms within a week. The NSAIDs could be withdrawn after 4 weeks as the treatment progressed. The doses were tapered for methotrexate (5 mg/week) and prednisolone (2.5 mg on alternate days) every 8 weekly subsequently during 15 months of follow-up without recurrence/deformities or drug toxicity. For years, the use of corticosteroids in psoriasis has been criticized for their propensity to exacerbate the skin disease on withdrawal. However, monitored use of corticosteroids, even in low doses, combined with DMARDs may be a good therapeutic option in early stage of the PsA rather than 'steroid rescue' later. This will help in early control of joint inflammation, prevent joint damage and maintain long-term good functional capacity and quality of life. This may be useful when the cost or availability of biologics precludes their use. However, we discourage the use of corticosteroids as monotherapy.

Post-kala-azar dermal leishmaniasis (PKDL) is an unusual dermatosis occurring following an attack of visceral leishmaniasis (VL). There are only few reports of PKDL after successful treatment with miltefosine. We report two cases of PKDL that developed after successful treatment of VL with miltefosine.

Acrospiroma denotes a group of benign ductal tumours of the eccrine sweat glands that may or may not be connected to the skin. Although various eccrine sweat gland tumours including benign acrospiroma are widely reviewed, malignant acrospiroma is rarely reported. Malignant acrospiroma have the propensity to recur locally and metastasizes to regional lymph nodes. The primary treatment is wide local excision with or without lymph node dissection. Local radiation is added in the presence of high risk features to reduce the risk of recurrence. We describe a case of a malignant acrospiroma involving wide areas of chest and abdominal wall with metastases to bilateral axillary lymph nodes in a 47 year old man showing minimal clinical response to combination chemotherapy and paclitaxel.

Ectodermal dysplasia (ED) is a rare, congenital disease that involves the sweat glands, scalp hair, nails, skin pigmentation, and craniofacial structure. Oral symptoms of ED include multiple tooth abnormalities (such as hypodontia, anadontia, impacted teeth, and peg-shaped or conical anterior teeth) and lack of normal alveolar ridge development. A 12-year-old male patient, in the absence of any other systemic abnormalities, exhibited typical characteristics of ED, visited our department of pedodontics and preventive dentistry at Panineeya Mahavidyalaya Institute of Dental Sciences and Research Centre. In the clinical and radiographic evaluation, it was occurred that he had only maxillary and mandibular first molars in his mouth. A maxillary and mandibular denture with clasps for retention was fabricated for prosthodontic rehabilitation after considering his growth and the number and condition of his present teeth. At the 18-month follow-up no major complications occurred and further future treatment included implants retained fixed partial dentures.

Fusarium solani is commonly found in soil, and it is associated with infections in immunocompromised individuals. Fusaroium solani causing infection in immunocompetent adult male is rare and usually overlooked. We report a case of mycetoma caused by Fusariom solani in an immunocompetent adult male from South India.

Gorlin Syndrome, a rare genodermatosis, otherwise known as Nevoid basal cell carcinoma syndrome (NBCCS) is a multisystem disease affecting skin, nervous system, eyes, endocrine glands, and bones. It is characterized by multiple basal cell carcinomas, palmoplantar pits, jaw cysts, and bony deformities like kyphoscoliosis and frontal bossing. We would like to report a case of Gorlin syndrome with classical features, as this is a rare genodermatosis.

Pityriasis rosea (PR) is an acute or subacute inflammatory skin disease characterized by erythematous papulosquamous eruptions localized on the trunk and arms. The eruptions are self-limiting and usually disappear gradually in 2-10 weeks, without any treatment. Typical PR is much easier to diagnose than the rare atypical forms. There is a passing mention of PR with erythema multiforme-like lesions in the literature, but no extensive case series have been published till date. We present a series of five patients for whom we believe atypical PR is the likely diagnosis.

Angiokeratoma of Fordyce occurring over vulva is rare. Angiokeratoma of Fordyce commonly occurs in males over scrotum or penile shaft and presents as multiple verrucous reddish papules. They are usually asymptomatic and noticed accidentally. In the present article, we present and review the literature of giant angiokeratoma of Fordyce in middle-aged women due to its rarity.

Cheilitis granulomatosa (CG) is a chronic swelling of the lip due to granulomatous inflammation. It is a rare inflammatory disorder first described by Miescher in 1945. It is a monosymptomatic form or an incomplete variant of Melkersson-Rosenthal syndrome; a triad of recurrent orofacial edema, recurrent facial nerve palsy and fissuring of the tongue. As the etiology remains unknown, treatment of CG is challenging. We present a case of CG in a 43-year-old female patient secondary to allergy to certain food items. The present case highlights the importance of thorough investigations in the diagnosis of this lesion as the findings mimic many other granulomatous conditions.

Cutaneous angiosarcomas (CAS) are uncommon, aggressive tumours. Very rarely, they arise from the lower extremity. Such tumours are usually associated with chronic lymphedema, a phenomenon known as Stewart-Treves Syndrome. Treatment is usually radical surgery with adjuvant therapy (radiotherapy/chemotherapy). Recurrence rate after primary treatment is high. Because of post therapy changes, conventional imaging has limited specificity for diagnosing recurrence. ¹⁸ F-Fluorodeoxyglucose ( ¹⁸ F-FDG) positron emission tomography-computed tomography (PET-CT) might be useful in such patients. It can demonstrate local recurrence along with distant metastasis, if any and can have significant impact on patient management. We here present three cases of recurrent CAS of lower extremity diagnosed with ¹⁸ F-FDG PET-CT.

Onychomycosis is frequently seen in dermatological clinical practice worldwide. The causative agents are usually two pathogenic groups of fungi namely, dermatophytes and yeasts of the genus Candida. In some cases, non-dermatophytic molds belonging to different genera and species may be the etiological agents. We report an unusual case of onychomycosis in an HIV-positive psoriatic patient caused by Rhizomucor pusillus, which has not been mentioned in the literature before. Our finding underline the fact that fungal species appearing as contaminants should be evaluated by proper clinical-mycological correlation to ensure an accurate diagnosis.

Dermatofibromas are benign skin lesions that consist of pigmented papules or nodules. They produce the dimple sign when laterally squeezed and are usually found on the legs. These clinical features lead to the diagnosis in most cases. However, the differential diagnosis with other lesions, such as atypical nevi and melanoma can be difficult, and the dermoscopy may help the diagnosis. There are several dermoscopic patterns associated with dermatofibromas, the most common being a central white scar like patch with delicate pigment network at the periphery. This article describes the case of a patient who had eleven clinically similar dermatofibromas, with four distinct patterns when submitted to dermoscopic examination.

Secondary follicular mucinosis developing in adult patient with atopic dermatitis (AD) was observed on histology. Due to severity of disease, patient was started on oral cyclosporine 300 mg daily in 3 divided doses. Two weeks later patient started developing multiple spiny follicular keratoses mainly on face but also on extremities and trunk along with hair casts on scalp. Repeat biopsy from such keratotic lesions confirmed diagnosis spiny follicular hyperkeratosis (SFH). On investigations no evidence of multiple myeloma or any other malignancy was found. Cyclosporine was stopped and lesions cleared over 2 weeks. We report this case due to rare association of AD with follicular mucinosis and cyclosporine induced SFH with hair casts.

Pulse dye laser has proved effective for plaque-type psoriasis, but it has not been evaluated in nail psoriasis. We are reporting treatment of 10 psoriatic nails in one patient with pulse dye laser.

We report a 55-year-old Japanese woman with a two-month history of multiple pruritic erythema and erosion on her face and neck. Based on the clinical appearance, we initially diagnosed her as having pemphigus erythematosus. However, the results of a histopathological examination and a direct immunofluorescence study did not support the initial diagnosis. Additionally, anti-desmoglein 1 and 3 antibodies were all negative. Subsequently, a microscopic examination of scales revealed filaments of fungi and a fungal culture was negative for macroconidium. Using molecular biology techniques, we identified the fungus as Microsporum canis, which causes a zoonotic infection. The immune reaction to the fungi could be drastic and therefore, the eruption sometimes displays atypical clinical manifestations.

Merkel cell carcinoma (MCC) is an uncommon aggressive neuroendocrine tumor of the skin that classically presents on chronic sun-damaged skin as a skin-colored, red or violaceous, firm and nontender papule or nodule with a smooth and shiny surface. Ulcerations can be observed very seldom and only in very advanced lesions. We present a unique case of a MCC presenting with two unusual clinical features: The Telangiectatic surface and the pedunculated aspect.

Monilethrix is a rare hereditary condition generally considered to be an autosomal-dominant disorder with variable penetrance. Here, we report a case of monilethrix in a 13-year-old boy with an affected sibling. A therapeutic trial with oral N-acetyl cysteine was attempted. There was slight improvement after 2 months of therapy. The hair density, however, did not show any further improvement subsequently. Monilethrix remains as a therapeutic challenge for dermatologists.

Hydroxyzine-induced drug eruptions are very rare. We report here a typical case of drug-related Baboon syndrome or symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) which was induced by hydroxyzine in a 60-year-old man. The diagnosis was confirmed by positive patch and oral accidental provocation tests with hydroxyzine. Patch tests and oral provocation tests with cetirizine and levocetirizine were negative. A review of the literature identified only 17 reported cases of hydroxyzine-induced drug eruptions. To the best of our knowledge, we report here the first case of hydroxyzine-induced SDRIFE.

Alveolar soft-part sarcoma (ASPS) is an extremely rare disease arising from connective tissues with a propensity for recurrence and metastasis. Clinically, it can be confused with hemangioma or arterio-venous malformations. Thus, a high index of suspicion and histopathological examination are required to make a definitive diagnosis. We report a case of recurrent ASPS in a young female with multiple sites involvement without any features of metastasis who has been treated with excision of the symptomatic lesions followed by chemotherapy.

Basal cell carcinoma (BCC) is the most common malignant tumor of skin. The most common site (80%) is head and neck. BCC exhibits a varied morphology such as adenoid, keratotic, sebaceous, basosquamous, apocrine, eccrine or fibroepithelial. Tumors with a similar histopathological picture are cutaneous adenoid cystic carcinoma and primary cutaneous cribriform apocrine carcinoma. Immunohistochemistry, along with clinical findings, acts as an adjunct in reaching an accurate diagnosis. Here, we present an interesting case of adenoid BCC in a 55-year-old man.

We report here 3 cases with the classic signs of Goldenhar syndrome in the form of multiple accessory tragi, bilateral ocular dermoids, mandibular hypoplasia (micrognathia), and facial microsomia. One of the patients also had vitiligo, which is yet to be reported as an association.

We wish to report two cases of rickets due to vitamin D deficiency secondary to underlying ichthyotic skin disorder. The first case is of an 8-year-old male with history of multiple fluid-filled lesions over the body that would rupture to heal with thickening and scaling of skin, suggestive of epidermolytic hyperkeratosis, and the second is of a 14-year-old female with thick, large, quadrilateral scales over the extremities and back clinically consistent with lamellar ichthyosis. Both showed improvement with parenteral vitamin D3 and oral calcium supplements in addition to topical emollients.

The most significant and debilitating complication of herpes zoster (HZ) is herpetic neuralgia that accompanies and may persist in 10-15% of all zoster patients, particularly those over 60 years of age. The described 3 cases had an uncommon complication of spontaneous tooth exfoliation after trigeminal HZ that rarely finds mention in dermatology literature.

Chondroid syringoma, or mixed tumor of skin, is a relatively rare, usually benign sweat gland tumor, most often seen in the head-and-neck region. Rare malignant examples have been reported, commonly involving the extremities. We report here a case radiologically mimicking a malignant neoplasm, but histologically-proven benign subcutaneous chondroid syringoma, arising in the anterior aspect of the upper thigh of a 59-year-old male.

We report a case of granuloma faciale over distal extremities in a 60-year-old man without facial lesions who did not show any response to dapsone.

Cutaneous piloleiomyoma is a rare benign tumor of skin originating from skeletal muscle of arrector pili attached to hair follicle. It can be single or multiple, solitary piloleiomyoma are common over genitalia. Multiple cutaneous piloleiomyomas are rare and they can cause pain on exposure to cold or with emotional disturbance. The prognosis of cutaneous piloleiomyomas after surgical excision is good. Here, we present a rare case of generalized multiple cutaneous piloleiomyoma in a young male.

Plexiform neurofibroma is common over the branches of trigeminal and cervical nerves over the face. Plexiform neurofibroma over palm is rare and affects the individuals with fine motor functions of hand. Here, we report a case of isolated plexiform neurofibroma over the palm with review of literature.

We report a case of hidroacanthoma simplex with giant lesion that was found on the left lumbar part which was treated with surgical excision.

Psychogenic excoriation is a condition where the patient picks the skin repetitively to produce excoriations. Treating this clinical entity is challenging as these patients often have an associated psychological abnormality. The five cases in this case series include two children and three adults. They presented with skin lesions ranging from excoriations and ulcers to scars and pigmentation. Detailed evaluation was done by clinical psychologist. Two cases had anxiety traits, one had alcohol dependence, one had difficult temperament and one had depressive symptoms. Habit reversal was introduced. Psychiatry referral was given for three cases and started on selective serotonin reuptake inhibitors. On follow-up, the urge to scratch reduced substantially and skin lesions were also improving. It is important to identify the underlying psychological disorder accounting for skin picking behavior. Incorporating psychotherapeutic techniques into clinical practice will improve the quality of life of many of these patients.
