Hepatoid adenocarcinoma of the papilla of Vater

Abstract

An adenocarcinoma of the papilla of Vater showing hepatoid differentiation similar to that described for hepatoid adenocarcinoma of the stomach is reported. The tumor was a poorly differentiated adenocarcinoma with clear cells containing occasional hyaline droplets and exhibiting bile secretion. Alpha-fetoprotein (AFP), alpha 1-antitrypsin (alpha 1-AT) and carcino-embryonic antigen (CEA) were demonstrated by immunoperoxidase staining. This appears to be the first report of a hepatoid adenocarcinoma at this location.
