Hepatoid adenocarcinoma was described by Ishikura in 1985 for the first time. It is a very rare variant of adenocarcinoma characterized by morphological and functional features of hepatocyte differentiation. It is most commonly presented as gastric adenocarcinoma with otherwise unexplained elevation of serum alpha-fetoprotein level. Most of the patients with gastric hepatoid adenocarcinoma were diagnosed in advanced stages having vascular invasion and/or extensive metastasis in liver or lymph nodes. Accordingly, the prognosis of hepatoid adenocarcinoma is dismal. We experienced a typical case of gastric hepatoid adenocarcinoma and described the clinical features.
