Description
Discoid lupus erythematosus, also referred to as DLE, is a chronic but localized skin condition where sores (lesions) form on the scalp, face, elbow, or fingertips. In DLE, the autoimmune system attacks connective tissue. The lesions are red, inflamed patches with a scaling and crusting appearance. If present in areas with a significant amount of hair, the lesions can cause scarring and hair loss in that area. Because the symptoms are similar to other skin diseases and other types of lupus, a skin biopsy must be performed to confirm a diagnosis.
The primary difference between discoid lupus erythematosus (DLE) and systemic lupus erythematosus (SLE) is that DLE mainly affects the skin, while SLE also affects the organs, such as the heart, blood vessels, nervous system, and kidneys. Patients can have both DLE and SLE.
