Psoriasis is an autoimmune condition that causes scaly, raised, reddish patches of skin. There are several forms of psoriasis. The most common form is plaque psoriasis, which causes scaly patches on the scalp, knees, back, and elbows. About 30% of individuals with psoriasis will eventually go on to develop inflamed joints, or psoriatic arthritis. Treatment for psoriasis may include light therapy and the application of topical agents to provide relief.
