Psoriasis is a non-contagious, chronic skin condition that produces plaques of thickened, scaling skin. The dry flakes of skin scales result from the excessively rapid proliferation of skin cells. Psoriasis is generally thought to be a genetic disease which is triggered by environmental factors. Psoriasis is estimated to affect 2-4% of the population of the western world. The rate of psoriasis varies according to age, region and ethnicity; a combination of environmental and genetic factors is thought to be responsible for these differences. Psoriasis affects both sexes equally. It can occur at any age, although it most commonly appears for the first time between the ages of 15 and 25 years. Approximately one third of people with psoriasis reports being diagnosed before age 20. In India the prevalence of psoriasis varies from 0.44 to 2.8%, it is twice more common in males compared to females, and most of the patients are in their third or fourth decade at the time of presentation. In addition to the appearance and distribution of the rash, specific medical signs may be used by medical practitioners to assist with diagnosis. These may include Auspitz's sign (pinpoint bleeding when scale is removed), Koebner phenomenon (psoriatic skin lesions induced by trauma to the skin), Candle grease sign and itching and pain localized to papules and plaques.
