Experience of the pancreas duodenectomy for so-called carcinosarcoma of the common bile duct:a case report and review of literature.

A 79-year-old man presented with malaise and jaundice at a local hospital. His blood tests showed severe inflammation, liver failure, and high expression of several tumour markers. Radiological findings revealed dilated common and intrahepatic bile ducts and a lower bile duct constricted by a soft tissue mass. Histological findings by endoscopy showed a suspected adenocarcinoma, which was determined as class IV by cytology. The patient was referred to our hospital for surgical treatment. He underwent pancreaticoduodenectomy and the final diagnosis was so-called carcinosarcoma of the bile duct. He had liver metastasis and died at 26 postoperative months.
