A case of synchronous double cancer of the gallbladder with a colonic cancer was experienced. A 68-year-old woman was admitted to the hospital because of melena and pollakisuria, and was examined in full. Curative operation was performed under a preoperative diagnosis of double cancer of the gallbladder and colon. Histologically, two tumors were found in the gallbladder. Those tumors were papillary adenocarcinoma with moderately differentiated tubular adenocarcinoma and poorly differentiated adenocarcinoma, and no continuity was noted between them. There were 12674 double cancers from 1987 to 1992 on the Annual of the Pathological Autopsy Cases in Japan. Of 12674 cases five cases had double cacer of the gallbladder, but none had tripple cancer of the gallbladder, gallbladder and sigmoid colon. Any case reports like this were not seen in the literature as far as we could review.
