title: Sarcoidosis-associated hepatitis C virus infection.
abstract: Although several reports of sarcoidosis have been reported in hepatitis C virus (HCV)-infected patients treated with interferon-alpha, this association has never been described in nontreated HCV patients. We report two cases of sarcoidosis associated with chronic hepatitis C infection. The patients developed multivisceral sarcoidosis (cutaneous, lungs, nodes) at two and at least six years after the presumed date of infection. One patient obtained remission of sarcoidosis with corticosteroid treatment but the other remained corticodependent. The levels of hepatic enzymes were not significantly modified throughout the course of corticosteroid therapy. In conclusion, these case reports suggest that HCV itself could induce a granulomatous reaction in chronic HCV-infected patients through the stimulation of the cellular immune system. It could be of interest to test for HCV infection all patients diagnosed with sarcoidosis and to watch over every treated or nontreated hepatitis C infected patient for the development of granulomatous lesions.
