Abstract

Hepatoid adenocarcinoma is a rare type of extrahepatic cancer characterized by hepatocellular carcinoma-like histology. We present a case of a large solitary mass in the peripancreatic region found to be an isolated lymph node metastasis from an unknown primary hepatoid adenocarcinoma masquerading as an acinar carcinoma of the pancreas.
