[Lymphoma of the biliary tract: report of 2 cases].

We report two cases one a primary non Hodgkin lymphoma of the hepatic common duct and the other a secondary involvement of the biliary tract in a patient with a Hodgkin's disease. In the first case a local resection of the biliary lymphoma was undertaken being the patient alive six months after the procedure. The second case died early after the operative biliary external drainage in a septic shock before any specific treatment could be initiated.
