One year after gastric resection for cancer, a 67 year old patient was hospitalized because of a large hepatic tumor with extremely high serum alpha-foetoprotein levels (13,245 ng/ml). Histological and immunohistochemical studies of the gastric tumor revealed hepatoid foci with alpha-foetoprotein and protease inhibitor-producing cells. Histopathological and immunohistochemical features of this and the 8 previously reported cases of hepatoid adenocarcinoma of the stomach are analyzed.
