[Systemic sarcoidosis with cutaneous lesions: literature review].

Sarcoidosis is a systemic disease of unknown etiology. The diagnosis is based on consistent clinical, biological and radiological findings supported by histologic evidence of noncaseating epithelioid granulomas. Skin lesions occur in about a quarter of patients with sarcoidosis. The purpose of this article is to analyse through the clinical presentation of dermatological lesions, a potential link with systemic disease.
