Synopsis

Discoid lupus erythematosus (DLE) is a disfiguring autoimmune skin disease and the most common form of chronic cutaneous lupus erythematosus (CLE). DLE most commonly affects women in the second, third, and fourth decades of life, although it may occur at any age. Black patients with DLE may be more at risk for severe disease, and there may be a positive family history of systemic lupus erythematosus (SLE) or other connective tissue disease.

Discoid rash is one of 11 clinical criteria for the Systemic Lupus International Collaborating Centers (SLICC) classification of SLE and is a contributor to the musculoskeletal clinical domain within the European League Against Rheumatism / American College of Rheumatology (EULAR / ACR) classification criteria for SLE.

DLE may be localized or generalized. Localized DLE is limited to the face, scalp, ears, and neck, while in generalized DLE, there may be lesions both above and below the neck. It is rare for DLE to be isolated below the neck. There is a 20% likelihood of SLE with generalized DLE and 5% with localized DLE. Conversely, approximately 15%-30% of patients with SLE will manifest discoid lesions. Other risk factors for SLE include mucocutaneus involvement, arthralgias / arthritis, nail changes, anemia, leukopenia, an elevated ESR, and a positive antinuclear antibodies (ANA) test.

Squamous cell carcinoma may rarely develop in chronic DLE scars, especially in sun-exposed areas.

The presence of erythema multiforme-like lesions in a patient with lupus, along with a speckled pattern of ANA, positive anti-Ro/SSA or anti-La/SSB, and positive rheumatoid factor (RF) is known as Rowell syndrome. This syndrome has been described in patients with DLE, subacute cutaneous lupus erythematosus (SCLE), and SLE. Its existence as a distinct entity has been debated in the literature; some authors believe the association is coincidental. Prednisone with or without hydroxychloroquine, dapsone, or immunosuppressive drugs such as cyclosporine have been cited as therapy.
