Hepatoid adenocarcinomas of the stomach are gastric carcinomas with both adenocarcinomatous and hepatocellular differentiations. The tumor was characterized by high serum alpha-fetoprotein (AFP) levels. A 73-year-old male patient was admitted to the hospital with abdominal pain. Gastrofiberscopy revealed a gastric tumor occupying the antrum and pylorus. Radical subtotal gastrectomy was done and the result of biopsy was poorly differentiated adenocarcima of stomach and stage 3B. At postoperation 8 month, AFP was elevated and liver mass was detected on CT. Right extended hepatectomy was done under the impression of primary liver tumor. But, the biopsy revealed metastatic hepatoid adenocarcinoma of the stomach. Re-examination of the resected stomach was done and the result was hepatoid adenocarcinoma of the stomach. Two months later, after the hepatic resection, multiple metastases developed. This type of tumor has frequent early liver metastasis and poor prognosis. Therefore, early diagnosis and more careful investigation for liver metastasis are recommended.
