Extrahepatic bile ducts carcinoma (EHBC) arises usually in the upper third of the biliary tract. They are rarely multicentric associated or not to a gallbladder carcinoma. We report the case of a 53 years man operated for a head pancreas. Laparatomy revealed a tumour of the middle common bile duct extending to the cystic duct. Histologically it was a multicentric carcinoma of variable types occurring in several sites of the biliary tract. Patient had undergone a simple resection without any complications 9 months later. Although EHBC are morphologically similar to those of the gallbladder, their risk factors, epidemiology and treatment are different. Prognosis depends on proximal involvement of perihilar bile ducts which makes the treatment only palliative.
