We report a case of resected undifferentiated carcinoma of the gallbladder with anomalous arrangement of the pancreaticobiliary duct. A 42-year old man was diagnosed with a tumor projecting into the gallbladder by ultrasonography and computed tomography. Anomalous arrangement of the pancreaticobiliary duct without dilation of the biliary duct was observed by endoscopic retrograde cholangiopancreatography. Abdominal angiography showed a hypervascular tumor, necessitating cholecstectomy with resection S4a+S5 of the liver, resection of the extrahepatic common bile duct, lympadenectomy, and hepaticojejunostomy. The tumor was 3.5×2.5 cm and presented macroscopically as a nodular. Histology showed atypical tumor cells and a diagnosisof undifferentiated gallbladder carcinoma. The clinical stage was si, hinf1a, binf0, pv0, a0, bm0, hm0, stageIVa. Immunohistologically, EMA, cytokeratin, CA19-9, and CEA stains were positive but vimentin and AFP stains were negative.
