It affects mainly men over 50 and clinical manifestations are due to obstruction and/or local infections. The pathogenesis is uncertain. We report a case of TO found incidentally in an autopsy of a 73 year-old woman, who had an extrahepatic biliary ductal carcinoma (Klatskin tumor).459-462porKlatskin's tumorOsteochondroplasticaTracheopathiaResenha2-s2.0-67649961751
