[Synchronous early double cancers of the stomach and gallbladder].

Presented is a case of a 76-year-old male who had a double cancer, in the stomach and the gall bladder. The gastric tumor was found to be a IIc early cancer that showed invasion into the submucosa, and was, histologically, tubular adenocarcinoma. The carcinoma of the gall bladder was limited to the mucosal layer, and was, histologically a papillary adenocarcinoma. Partial gastrectomy and cholecystectomy were performed. In a review of the literature in Japan, synchronous double cancer, an early gastric cancer and an early carcinoma of the gall bladder, is very rare and 3 only cases have been summarized, including this case.
