[Cutaneous manifestations of sarcoidosis].

Skin involvement in sarcoidosis is common and may occur as very early symptoms. Since skin biopsy is easy, these manifestations allow a rapid diagnosis. Erythema nodosum is a non specific symptom, and rare other non specific manifestations may occur. Skin lesions are mostly specific, with an epithelioid granuloma, lack of classification and a few giant cells. The clinical spectrum is very large, and the diagnosis is often made with regards to histopathological features only.
