Discoid lupus
Discoid lupus erythematosus (also called discoid lupus or DLE) is an autoimmune skin condition. It is the most common type of lupus. It shows as painful, red areas of skin. Many times, it appears on the scalp, cheeks, or ears. A person can lose hair if they have DLE on their scalp. The red areas can scar and last for years if they are not treated.
