title: No ancillary finding is valid to distinguish a primary ovarian hepatoid carcinoma from metastatic hepatocellular carcinoma.
abstract: Primary ovarian hepatoid carcinomas (POHC) are extremely rare. 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.
