Discoid lupus erythematosus (DLE) is a chronic autoimmune skin disorder that causes a red, scaly rash on the face, scalp, and other areas of the body. It is caused by the body's immune system attacking its own tissues. The rash is usually round or oval in shape and can be itchy or painful. In some cases, the rash can cause scarring and permanent hair loss. DLE is more common in women than men and is usually seen in people between the ages of 10 and 50. Treatment for DLE includes topical and oral medications, as well as lifestyle changes.
