Psoriasis is a chronic, recurring disease that causes one or more raised, red patches that have silvery scales and a distinct border between the patch and normal skin. ; Psoriasis is common and varies widely among different populations worldwide. It is likely that psoriasis is underreported among people with dark skin compared with people with light skin. ; Psoriasis begins most often in people aged 16 to 22 years and aged 57 to 60 years. However, all people of all ages are susceptible. ; The patches of psoriasis occur because of an abnormally high rate of growth of skin cells. The reason for the rapid cell growth is unknown, but a problem with the immune system is thought to play a role. The disorder often runs in families, and certain genes are associated with psoriasis.
