Were you looking for information about Psoriasis? Psoriais is a common misspelling of psoriasis.
Psoriasis is an inflammatory skin disease that occurs in 2 to 2.6 percent of the U.S. population. It is characterized by scaling and swelling of the skin, which results from overactive T cells (a type of white blood cell that helps protect the body against infection and disease). People with psoriasis may have patches of thick, red skin with silvery scales on their face, lower back, knees, and elbows. Light therapy and medications, both topical and oral, are often used to treat this condition.
