Discoid Lupus Erythematosus is the most common form of Cutaneous Lupus Erythematosus (LE), and typically affects the nose, ears, and/or cheeks, though it may appear in other areas such as upper torso, neck, and hands. The condition consists of scaly patches of skin which are red in color and result in dyspigmentation and scarring of the affected area. The condition may involve hair follicles, resulting in permanent alopecia in some cases, and may also affect the lips and mouth interior, resulting in scaling and ulceration. In cases involving the mouth, lesions may be vulnerable to developing Squamous Cell Carcinoma.

Discoid Lupus Erythematosus is an autoimmune disorder in which the nuclei of skin cells in the affected area are attacked by the immune system. This response is very often  triggered by exposure to sunlight, and the condition's effects are more severe in those who smoke. The condition most commonly appears in adult women, but may also develop in males, children, and older persons.

    The goal of treatment of Discoid Lupus Erythematosus is to relieve visible symptoms and to prevent scarring if possible. Health care professionals may recommend limiting sun exposure and ceasing smoking to prevent these stimuli from exacerbating the condition. Several treatments are available which may be of benefit to affected persons, including topical medications such as steroids, calcineurin inhibitors(such as Pimecrolimus and Tacrolimus). Other medications which may be prescribed with varying effect include corticosteroid Injections, antimalarials, Systemic steroids, and even vascular laser therapy. A wide range of medications may be used to treat severe cases, including retinoids, Methotrexate, Thalidomide, Cyclosporine, Gold, Dapsone, Cyclophosphamide, Clofazamine, IV Immunoglobulin, and Biological response modifiers.
