Sample pathology report
  • Liver, mass, core biopsy:
    • Lymphoepithelioma-like hepatocellular carcinoma (see comment)
    • Comment: The tumor shows histologic features of lymphoepithelioma-like carcinoma with pleomorphic tumor cells arranged in nests and cords within a dense lymphoid stroma. The tumor cells are positive for pancytokeratin, HepPar1 and glypican 3, and negative for CK7, CK19 and mucicarmine. EBV in situ hybridization is negative.
