Background: Vitiligo is an acquired, idiopathic, and common depigmentation disorder. The values of various epidemiologic parameters are often doubtful due to the methodological weaknesses of the studies., Aims: To elicit the magnitude of various epidemiological parameters and important correlates of vitiligo., Materials and Methods: Every vitiligo patient attending the outpatient department of medical colleges spread over most of the Indian states were examined over a period of 1 year. Various epidemiological and clinical variables were examined and compared with age and sex-matched controls (registered in the Clinical Trial Registry of India CTRI/2017/06/008854)., Results: A total of 4,43,275 patients were assessed in 30 medical colleges from 21 Indian states. Institutional prevalence of vitiligo was 0.89% (0.86% in males and 0.93% in females, P < 0.001). The mean age at presentation and mean age at onset were 30.12 ± 17.97 years and 25.14 ± 7.48 years, respectively. Head-neck was the most common primary site ( n = 1648, 41.6%) and most commonly affected site ( n = 2186, 55.17%). Most cases had nonsegmental vitiligo ( n = 2690, 67.89%). The disease started before 20 years of age in more than 46% of cases. About 77% of all cases had signs of instability during the last 1 year. The family history, consanguinity, hypothyroid disorders, and depressed mood were significantly ( P < 0.001) higher among the cases. First, second, and third-degree family members were affected in 269 (60.04%), 111 (24.78%), and 68 (15.18%) cases, respectively. Work-related exposure to chemicals was significantly higher among cases ( P < 0.008). Obesity was less common among vitiligo cases [ P < 0.001, odds ratio (OR) 0.78, 95% confidence interval (CI): 0.71-0.86]., Conclusion: This is one of the largest studies done on vitiligo in India. The prevalence of vitiligo was found to be 0.89% among hospital attendees. Prevalence of vitiligo was higher among females than in males and prevalence of family history, consanguinity, hypothyroid disorders were higher in vitiligo than among controls., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Indian Journal of Dermatology.)

A 17 years old female presented with multiple asymptomatic cutaneous cysts all over body, sparing the head and neck region. The microscopic examination of the cysts showed the features of steatocystoma multiplex. This disorder, although it is asymptomatic, is a cosmetic threat to the patient. Only a few cases of the patients with an autosomal dominant mutation, who had keratin 17, have been reported. We are reporting here, a case of steatocystoma multiplex in a 17 years old female, along with its review of literature.
