Psoriasis is a chronic autoimmune disease in which the immune system sends faulty messages that speed the growth of skin cells. This faster growth causes patches of extra skin to appear.
There are five forms of psoriasis, including plaque psoriasis, the most common type, in which raised red patches of skin are covered with a silvery buildup of dead skin. Even though there’s no cure for psoriasis, there are medications and treatments options to control it. Psoriasis, the most common autoimmune disease in the United States, can occur on any part of the body.
