Description
Summary:We report the case of a 19-year-old woman who presented with a hepatic mass without cirrhosis. Light microscopy revealed a cholangiocarcinoma having both well-differentiated adenocarcinoma and lymphoepithelioma-like undifferentiated carcinoma components. By immunohistochemistry, the tumor showed strong and diffuse expression for cytokeratin AE1, 5D3, and CK22. The tumor cells were positive for p53 protein (more than 75% of the cells) but negative for bcl-2 and LMP-1. Abundant Epstein-Barr virus EBER 2 oligonucleotides were detected in both tumor components, but not in the lymphoid stroma or the nontumor liver. To the best of our knowledge, this is the third report of an Epstein-Barr virus-associated primary hepatobiliary adenocarcinoma with lymphoepithelioma-like component.
