Cutaneous Manifestations of Systemic Lupus Erythematosus

Abstract

ABSTRACT Inflammation driven by immune-mediated mechanisms can lead to a wide variety of skin manifestations. Cutaneous lupus erythematosus (CLE), for example, is an autoimmune connective tissue disease that may be limited to the skin or be part of the widespread multiorgan involvement seen in systemic lupus erythematosus. Clinical findings are divided into lupus-specific (acute, subacute, and chronic) and nonspecific skin lesions. The diagnosis of CLE requires a thorough physical examination and, in some cases, skin biopsy and laboratory evaluation for any underlying systemic involvement. CLE treatment is dependent on the cutaneous manifestations and severity of disease. In addition to lifestyle measures, particularly avoidance of sunlight, topical and systemic therapies have proven beneficial. Prognosis is varied by disease severity, although chronic CLE notoriously results in cosmetic damage. Early recognition and management of CLE is important as it may also be the presenting manifestation of systemic lupus erythematosus. Patient care includes education and close collaboration with primary care providers, dermatologists, and rheumatologists.
