We report on a rare case of metachronous double carcinoma of the biliary tract, occurring in a 65-year-old male. The patient was admitted to the hospital with jaundice in March 2004.

After 2 years, during follow-up, the findings of a positron emission tomography ( PET)-CT scan suggested a possible cholangiocarcinoma of the distal part of the biliary tract; CT and MRI scanning of the abdomen showed mild dilatation of the distal common hepatic duct; an ERCP showed mild dilatation of the retropancreatic remnant of the biliary tree with endoluminal defects. Eventually the patient underwent pancreaticoduodenectomy. The histopathological diagnosis of the resected specimen confirmed a cholangiocarcinoma; 10 lymph nodes were negative ( pT1N0M0). At 6 months post-op after the second operation the patient is progressing well with no signs of recurrence. Patients with cholangiocarcinoma - in whom survival is prolonged with surgical resection - should undergo careful follow-up for both recurrence and second primary cancer. PET scanning seems to play the most important diagnostic role.

Abstract

We report on a rare case of metachronous double carcinoma of the biliary tract, occurring in a 65-year-old male. The patient was admitted to the hospital with jaundice in March 2004. Ultrasonography, computed tomography ( CT) and magnetic resonance imaging ( MRI) scans of the abdomen showed a minimally dilated intrahepatic biliary tree with normal-appearing choledocus. Obstruction of the common hepatic duct was revealed by endoscopic retrograde cholangiopancreatography ( ERCP). The patient underwent a resection of the middle third of the extrahepatic duct and cholecystectomy ( cholangiocarcinoma, pT1N0M0), with the surgical margins of resection showing as negative. After 2 years, during follow-up, the findings of a positron emission tomography ( PET)-CT scan suggested a possible cholangiocarcinoma of the distal part of the biliary tract; CT and MRI scanning of the abdomen showed mild dilatation of the distal common hepatic duct; an ERCP showed mild dilatation of the retropancreatic remnant of the biliary tree with endoluminal defects. Eventually the patient underwent pancreaticoduodenectomy. The histopathological diagnosis of the resected specimen confirmed a cholangiocarcinoma; 10 lymph nodes were negative ( pT1N0M0). At 6 months post-op after the second operation the patient is progressing well with no signs of recurrence. Patients with cholangiocarcinoma - in whom survival is prolonged with surgical resection - should undergo careful follow-up for both recurrence and second primary cancer. PET scanning seems to play the most important diagnostic role.
