Chronic cutaneous lupus erythematosus
Abstract
Chronic cutaneous LE is a diverse disease, characterized by predominantly cutaneous disease with few systemic complications. Discoid lesions are commonly seen, but they are not specific for chronic cutaneous LE. These scarring and disfiguring changes are also present in neonatal LE, SLE, and complement deficiency LE. Because definitive diagnosis cannot be made by cutaneous examination alone, all patients should initially be evaluated for systemic disease. A small percentage of patients with chronic cutaneous LE will ultimately develop SLE, and therefore, patients should be re-evaluated periodically. The pathogenesis of the cutaneous lesions is not definitively known. There is suggestive evidence implicating T-cell mediated injury, especially in discoid LE. Antibody-dependent cellular cytotoxicity may also play a significant role in cellular damage in subacute cutaneous LE and neonatal LE, especially in the presence of anti-Ro antibody. Immunoglobulin deposition in association with membrane attack complex, has been associated with epidermal injury in some cases. Treatment of chronic cutaneous LE is largely symptomatic and nonspecific, focusing on reduction of inflammation. Further knowledge of pathogenesis will, hopefully, provide for specific immunologic therapy.
