How is discoid lupus different from normal lupus?

Lupus. Discoid lupus erythematosus (dle) is a chronic skin condition of sores with inflammation and scarring favoring the face, ears, and scalp and at times on other body areas. These lesions develop as a red, inflamed patch with a scaling and crusty appearance. The center areas may appear lighter in color with a rim darker than the normal skin. Discoid lupus can be divided into localized or generalized.
Skin only. Not all lupus patients have skin involvement , but skin lupus has only a small percentage of systemic or non skin symptoms.
