โรคสะเก็ดเงิน
Sign in to savePsoriasis is a long-lasting, noncontagious autoimmune disease characterized by patches of abnormal skin. These areas are red, pink, or purple, dry, itchy, and scaly. Psoriasis varies in severity from small localized patches to complete body coverage. Injury to the skin can trigger psoriatic skin changes at that spot, which is known as the Koebner phenomenon.
Psoriasis is a long-term autoimmune condition that causes patches of abnormal skin—typically red, pink, or purple, dry, itchy, and scaly—and is not contagious. It matters because it can range from affecting small areas to covering the entire body, and skin injuries can trigger new psoriatic patches to develop.
