Hepatoma presenting as a single cavitary lung mass

A patient who had had a lobectomy for a large cavitary lung mass died one month later. An autopsy was performed and pathologic review of surgical and postmortem specimens confirmed that the original lung lesion was metastatic hepatoma. Excavating solitary metastases from primary adenocarcinomas represent the rarest form of cavitary metastatic lesion, and this is the first report of hepatocellular carcinoma presenting as a single cavitary lung mass.
