Psoriasis is an inherited condition of excess skin cells. It develops when a person’s immune system sends faulty signals that tell skin cells to grow too quickly, causing red patches of various sizes.

Commonly affected areas are the elbows, knees, scalp, hands, and feet. At times psoriasis can affect any part of the skin.

Treatment depends on the type, severity and location of psoriasis. Topical medications, phototherapy, photochemotherapy (PUVA), and oral or injectable medications are available to patients.
