title: Epidemiological pattern of psoriasis, vitiligo and atopic dermatitis in India: Hospital-based point prevalence.
abstract: BACKGROUND
  The knowledge of the prevalence of common dermatoses will be useful for optimum use of valuable resources of the country.
  
  
  OBJECTIVE
  The aim of the study is to determine the pattern and prevalence of psoriasis, vitiligo and atopic dermatitis (AD) in India.
  
  
  METHODS
  This was a hospital-based study conducted on a single day in one medical college each in four zones of India.
  
  
  RESULTS
  The point prevalence of dermatological cases was 9.25%. The point prevalence of psoriasis, vitiligo and AD were 8%, 9.98% and 6.75% respectively. Chronic plaque type psoriasis was the most common (50%) clinical pattern. The most common site of involvement of psoriasis was the palms. Stable type of vitiligo was common which accounted for 65.21%. Lower lip was involved in 75% of mucosal vitiligo. Lower limbs were the most common site of onset of vitiligo. AD was most prevalent in the first decade (40.7%). Personal history of atopy was present in (59.5%) patients. Dry skin was present in 92.5% of patients.
  
  
  CONCLUSIONS
  Our data correlates with previous hospital-based prevalence studies of psoriasis, vitiligo and AD.
