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. %U https://ijgc.bmj.com/content/ijgc/16/4/1691.full.pdf
