A 67-year old woman with a complaint of epigastric distress was referred to our hospital under the diagnosis of gall bladder cancer. Enhanced computed tomography revealed the marked swelling of gall bladder, a high density mass which extended from the neck of gall bladder to the liver, and mass lesion in middle bile duct which was suspected the skip lesion. ERCP was not revealed the stenosis or occlusion of bile duct and showed a pancreaticobiliary maljunction. The exfoliative cytodiagnosis diagnosed the squamous cell carcinoma. The patient was diagnosed as gall bladder cancer with a pancreaticobiliary maljunction. Therefore, gallbladder bed resection, extrahepatic bile duct resection and biliary reconstruction were performed. The histopathological examination revealed adenosquamous cell carcinoma of gall bladder (Stage IIA) and high grade adenocarcinoma of common bile duct (Stage I). Adenosquamous cell carcinoma of the gallbladder is believed to have a poor prognosis. It is thought that strict follow-up was required.
