● Very rare type of hepatocellular carcinoma with pleomorphic tumor cells mixed with numerous lymphocytes; tumor cells tend to be small with focal syncytial growth; most cases are actually variant of cholangiocarcioma; usually EBV+
● Better prognosis than hepatocellular carcinoma
● 39 year old woman with liver transplant for end stage liver disease secondary to chronic hepatitis C (Diagn Mol Pathol 2004;13:183)
● 47 year old woman with abdominal pain (World J Gastroenterol 2008;14:4694)
● 64 year old man with cirrhosis, EBV- tumor (Arch Pathol Lab Med 1999;123:441)
● Cords and trabeculae of large polygonal epithelial cells with marked lymphocytic infiltrate
● Blurred border at tumor margin; otherwise normal liver
● Keratin (CK19), EMA
● Vimentin, AFP, CEA, CK20, HMB4, CD30
● Cholangiocarcinoma-lymphoepithelioma like variant: syncytial pattern of undifferentiated epithelial cells and glands in lymphocyte-plasma cell rich stroma; presence of glands differentiates this from lymphoepithelioma-like carcinoma
