Discoid Lupus Erythematosus (Dle)
Description
Skin condition that presents with a rash mostly along the face, ears, and scalp. This disorder is not systemic lupus erythematosus (SLE), although some patients with SLE will also have discoid lupus erythematosus (DLE). A small percentage of patients with DLE will also develop SLE. The skin changes may appear red, patchy, scaling, and crusting. Exposure to sunlight may cause the symptoms to worsen. The disorder is rare with women being more affected than men and most patients being between the ages of 20 and 40 years old. The cause of DLE is not known.
Symptoms
Symptoms are worse when exposed to sunlight and involve the face, ears, and / or scalp. The skin becomes red and scaly, and may be a darker color (hyperpigmented). With time scarring of the skin can occur.
Tests
A history and physical exam will be performed to evaluate the skin lesions. At times a skin biopsy may be performed to confirm the diagnosis.

- Skin biopsy
Treatment
Therapy depends on the severity of the symptoms and the skin changes. Treatment is directed toward decreasing the size of the rash, reducing permanent scars from developing, and preventing other areas of the skin from becoming involved. Medications used include: sunblock, corticosteroid cream, or localized injections of corticosteroid.
