[Hepatobiliary actinomycosis. Apropos of 3 cases with pseudocancerous aspects]

Three cases of hepatobiliary actinomycosis are reported. In all cases, carcinoma was initially suspected. One patient underwent cytoaspiration under sonographic guidance. Diagnosis was obtained by autopsy in one case, laparotomy and biopsy in the other cases. Confusion with cancer is frequent in actinomycosis, especially in hepatic lesions.
