De Novo Intrahepatic Cholangiocarcinoma After Deceased Donor Liver Transplant in an Adult Patient.

Survival after liver transplant has progressively improved over recent decades. Recurrent or de novo malignancy, however, remains a major cause of patient death after transplant. Here, we have described a patient who developed de novo intrahepatic cholangiocarcinoma in the graft liver after orthotopic liver transplant. The 48-year-old male patient had end-stage liver disease from hepatitis B-related liver cirrhosis and a Model for End-Stage Liver Disease score of 26 and was listed for liver transplant. Recurrent esophageal variceal hemorrhage, severe ascites, and splenomegaly had complicated the liver disease. He underwent emergent whole organ, deceased donor liver transplant for liver cirrhosis. The donor liver was procured through the standard donation after brain death process from a 72-year-old man who died of intracranial hemorrhage. The graft weighted 1500 g and had normal color, and cold ischemia time was 5 hours upon arrival at our hospital. The patient's early postoperative course was uneventful. Two months posttransplant, the patient presented to the emergency department with fever, abdominal pain, and skin rash. Computed tomography revealed a focal biliary stricture in the right hepatic duct. Magnetic resonance cholangiopancreatography identified intrahepatic duct dilatations. Subsequent endoscopic retrograde cholangiography demonstrated marked intra- and extrahepatic biliary dilatation. We considered it to be a benign stricture and inserted plastic stents. He recovered from biliary stricture-related cholangitis. Approximately 10 months posttransplant, the patient was admitted with fever and skin rash. Marked dilatation of the intrahepatic bile duct was shown with a poorly enhancing tumor in the right lobe of the graft. Percutaneous transhepatic biliary drainage and tumor biopsy confirmed intrahepatic cholangiocarcinoma. We believe this to be the first case of de novo intrahepatic cholangiocarcinoma in a patient with hepatitis B-related end-stage liver disease after liver transplant without primary sclerosing cholangitis.
