Background: Pigmented purpuric dermatoses (PPDs) are a group of chronic benign vascular disorders with varied clinical presentation. The etiopathogenesis of the condition largely remains unknown with a paucity of clinico-epidemiological and/or clinico-etiological studies. Objective: To study the clinico-epidemiological pattern, etiological factors and associations of PPD and correlate them with its severity in a set of Indian patients. Materials and Methods: In a cross-sectional study, all clinically diagnosed and histopathologically confirmed cases of PPD attending the outpatient department of dermatology from November 2015 to October 2016 were included in the study. Patients were evaluated based on a detailed history of the illness, comorbid conditions, drug usage, general physical, systemic, and cutaneous examinations, severity of disease (mild, moderate, or severe), laboratory parameters, and Doppler ultrasonography of the lower extremities. Results: There were a total of 60 patients with a female-to-male ratio of 1.14:1. The mean age of patients was 47 ± 12.10 (range: 15–70) years. Majority (70%) of the patients were housewives, bankers, and businessmen. The possible etiological and/or aggravating factors included prolonged standing (28.3%), drug intake (13.3%), alcohol ingestion (10%), strenuous exercise (5%), and varicose vein (3.3%). Schamberg's disease (90%) was the most common type observed. The most common systemic comorbidity identified was hypertension (58.3%) followed by diabetes mellitus (31.6%) and dyslipidemia (28.3%). A positive correlation was found between severity of the disease and presence of comorbidities (Mantel–Haenszel method,P< 0.0001). Conclusion: PPD was found to be associated with a variety of disorders and comorbidities. The number of the comorbidities increased with increasing severity of the disease. Besides exposing the patient to various risk factors, this may contribute to the vessel wall damage seen in the condition. All patients with PPD should, therefore, undergo an initial screen for these comorbidities.
