Mucinous cystadenoma of the gallbladder is rare. We report a case with segmental adenomyomatosis, and review two cases in the Japanese literature. A 85-year-old man with a history of cholelithiasis 12 years earlier was admitted for abdominal pain. On admission, he had no fever or jaundice, but had right subcostal tenderness. No mass was palpated. Laboratory data showed elevated billiary system enzyme. Abdominal ultrasonography, computed tomography, magnetic resonance cholangiography, pancreatography showed many stones and wall thickning of the body by a 17×20 mm sized mass of multiple small cysts on the gallbladder. He was operated on for cholelithiasis, segmental adenomyomatosis, gallbladder tumor. The gallbladder showed a smooth serosal surface and no lymph node swelling intraoperatively, so we conducted laparoscopic cholecystectomy. The resected specimen was confirmed to be mucinous cystadenoma with adenomyomatosis in microscopically.
