Psoriasis encompasses a group of chronic skin disorders that cause an itching and/or burning sensation, scaling, and crusting of the skin. The most commonly affected areas are the scalp, elbows, knees, hands, feet, and genitals. Although sometimes challenging, it can be treated successfully, sometimes for months or years at a time and occasionally even permanently.

Treatment depends on the type, severity, and location of psoriasis; the patient’s age, medical history, and lifestyle; and the effect the disease has on the patient’s general mental health. The most common treatments are topical medications, phototherapy, photochemotherapy (PUVA), and oral or injectable medication (for severe symptoms).
