Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by raised areas of abnormal skin. These areas are red, or purple on some people with darker skin, dry, itchy, and scaly. Psoriasis varies in severity from small, localized patches to complete body coverage.
Psoriasis affects 2–4% of the global population (6 million Americans, $30 billion/year), varying according to age, region, ethnicity, plus environmental and genetic factors. Psoriasis is associated with an increased risk of: arthritis, lymphoma, cardiovascular disease, Crohn's disease, celiac disease, ulcerative colitis, squamous cell carcinoma of the skin, cancer generally, and depression.
