It is an immune-mediated genetically determined skin disorder which affects the skin, nails as well as joints and has various systemic associations. Psoriasis can present at any age.

The peak age of onset in adults is in the third and fourth decade of life, with men having slightly greater chances of being affected.
How to identify psoriasis?
There are many clinical presentations of psoriasis. The most common type is the chronic plaque-type psoriasis which presents as circumscribed, well-demarcated erythematous plaques that occur on the elbows and knees, buttocks, scalp and lower back. The scales are abundant, loose, dry and silvery-white. It can manifest on hand and foot as well, it may occur in isolation or along with elsewhere on the body. Nail involvement is also common and can be the initial and the only site of involvement in some patients. Involvement of the joints can lead to significant joint damage and disability.
