Primary adenosquamous carcinoma arising from the papilla of Vater is an extremely rare tumor. Here we report a case of adenosquamous carcinoma of the duodenal major papilla. The patient was a 56-year-old man presenting with abdominal discomfort and anorexia. A computed tomography (CT) scan showed dilatation of the common bile duct (CBD) and both intrahepatic ducts with a suspicious mass in the distal CBD. Duodenoscopy revealed a mass with an irregular surface at the papilla. The patient underwent Whipple's operation. He was diagnosed as having adenosquamous carcinoma of the papilla of Vater. Eighteen months after pancreaticoduodenectomy, metastatic lymph nodes were noted in a follow-up CT scan.
