Bile duct adenocarcinoma mimicking veno-occlusive disease after autologous bone marrow transplantation for acute leukaemia.

Summary: A 52-year-old female underwent autologous BMT because of acute myeloid leukaemia FAB M4 in second remission. Since the patient had no HLA-identical sibling she received a purged autologous BM transplant. On day +5 she developed signs of a sepsis syndrome with fluid retention and was treated with broad-spectrum antibiotic therapy. However, her body weight remained high, ascites and an increase of total serum bilirubin and alkaline phosphatase developed. The icterus worsened to a total bilirubin level of 25 mg/100 ml. Sonographic and endoscopic imaging showed a dilated gall bladder but disclosed a post-hepatic cause for the icterus. A transjugular liver biopsy on day +71 revealed severe cholestasis and siderosis. The patient remained aplastic with constantly increased bilirubin levels. On day +73 septic shock syndrome occurred and the patient died of multiorgan failure 3 days later. At autopsy, a highly differentiated bile duct adenocarcinoma at the porta hepatis, so-called Klatskin tumour, was found, explaining the fatal course with intractable cholestasis.
