[Syncrhonous carcinosarcoma of the extrahepatic bile duct and gallbladder.].

UNLABELLED: Carcinosarcoma is a malignant neoplasm characterized for intermingled epithelial and mesenchymal components.

CASE REPORT: A preoperative suspected diagnosis will allow a radical therapy avoiding a very bad prognosis. We report on a male patient who was operated in our Service with diagnosis of synchronous carcinosarcoma of gallbladder and extrahepatic bile duct and a review of the Medical Literature.

DISCUSSION: A gallblader carcinosarcoma showing extension into common bile duct is very rare, a carcinosarcoma of the bile duct is exceptional, and a synchronous carcinosarcoma ofthe bile duct and gallbladder has not been reported previously.
