[Liver metastases from colonic adenocarcinoma simulating cholangiocarcinoma].

Macroscopic intrabiliary growth of liver metastases from colonic adenocarcinoma mimicking cholangiocarcinoma, a pattern of intrahepatic spread easily confused with primary neoplasia of the biliary tract, is extremely infrequent. Resection of liver metastases has a better prognosis than that of primary neoplasia of the biliary tract. We report a case of metastasis from adenocarcinoma of the colon that presented as a Klatskin tumor. The definitive diagnosis was established by immunostaining.
