TY - JOUR T1 - No ancillary finding is valid to distinguish a primary ovarian hepatoid carcinoma from metastatic hepatocellular carcinoma JF - International Journal of Gynecologic Cancer JO - Int J Gynecol Cancer SP - 1691 LP - 1694 DO - 10.1136/ijgc-00009577-200607000-00032 VL - 16 IS - 4 AU - J.

Especially rare are those with phenotypic properties of hepatocellular carcinoma (HCC) and an absence of clinical evidence of hepatic tumor. We report a case of a POHC with a common microscopic, immunophenotypic, and ultrastructural property of HCC in the absence of a liver mass. It is extremely difficult to differentiate POHC from metastatic HCC using any kinds of ancillary studies, with the exception of clinical identification of a hepatic tumor. ER -
