We report a case of multiple carcinoma of the gallbladder showing different histological types with pancreaticobiliary maljunction. A tumor of the gallbladder was detected by abdominal ultrasonography in a 58-year-old female previously diagnosed with gastric ulcer. A contrast CT scan of the abdomen revealed a thickened enhanced wall at the bottom of the gallbladder and swelling lymph nodes around it. A pancreaticobiliary maljunction of category IIa of the new Komi classification was disclosed by ERCP. A diagnosis of carcinoma of the gallbladder with pancreaticobiliary maljunction was made and a full thickness cholecystectomy, resection of extrahepatic bile duct and level 2 lymph node dissection were performed. We found three tumors in the gallbladder specimen. Based on pathological examination, a diagnosis of multiple carcinoma in three different histological types was made. This is the first reported case in Japan.
