Chronic cutaneous lesions of sarcoidosis.
Sarcoidosis involvement of the skin is common. The skin lesions of sarcoidosis may be nonspecific, showing a nondiagnostic inflammatory reaction pattern on histologic evaluation. Nonspecific skin lesions are often associated with an acute presentation of sarcoidosis and, in general, portend a good prognosis. Specific sarcoidosis skin lesions reveal typical sarcoid granulomas on histologic examination. These lesions tend to be chronic and require therapy for resolution. This article will review the epidemiology, diagnostic evaluation, and description of the various chronic skin lesions of sarcoidosis. Various images of these skin lesions will be demonstrated.
