Objective:We reported a case with AFP produced gastric hepatoid adenocarcinoma. Methods:A male patient,77 year-old, was admitted to our hospital due to an unreasonable elevation of serum AFP. The tumors were revealed by PETCT,but until the tumors were removed during the surgery, we did not recognize the primary lesion was the gastric cancer.Results:Radical distal gastrectomy was performed. The gastric lesion was confirmed by histology as a hepatic adenocarcinoma in its early stage. Conclusion:The rare etiology of the AFP elevation should be kept in mind in clinic, extrahepatic lesions should be excluded.
