Background: Psoriasis is a common papulosquamous chronic, recurrent inflammatory skin disease with genetic predisposition and environmental factors acting as triggers. The current prevalence of common dermatoses will be useful for giving appropriate treatment for the patients. The aim of the study is to determine the different clinical pattern and prevalence of psoriasis in our institution.

Methods: This study is a hospital-based descriptive study. We included 400 self-reporting patients of age group 6-87 years with psoriasis who attended our skin OPD. Period of study was 3 months from January 2019 to March 2019 in our medical college situated in Chengalpattu, Tamil Nadu.

Results: Chronic plaque psoriasis is the most common (63.2%) clinical pattern observed irrespective of age and sex. Scalp and Nail involvement were common. Co-morbidities associated include diabetes mellitus, hypertension, alcoholism, hypothyroidism, and depression.

Conclusions: Our data correlates with previous hospital-based prevalence studies of psoriasis.
