Sarcoidosis and chronic hepatitis C: treatment with prednisone and colchicine.

Sarcoidosis is a disease which still has uncertain etiology. Possible environmental causes are cited in the literature, like organic and inorganic particles and infectious agents. Recent studies have demonstrated the occurrence of sarcoidosis in patients with chronic C hepatitis; however, this association remains without statistical or causal evidence. In this report a case of sarcoidosis associated with chronic hepatitis C will be described, with subcutaneous lesions, considered rare, and good response to treatment with colchicine and prednisone. The hepatitis C virus was isolated in sarcoid tissue and the association between the two diseases will be discussed.
