A Quick Look at Psoriasis

Psoriasis at a Glance

About 3 percent of Americans have a long-lasting skin disease called psoriasis. It’s characterized by patches of inflamed, scaly skin, which usually feel itchy or painful. The look of these patches varies, depending on the type of psoriasis you have. The patches can occur on the arms, legs, trunk, scalp, palms, soles of the feet, genitals, and even inside of the mouth. The nails and joints are sometimes affected as well.
