Cholestasis caused by biliary botryoid sarcoma

: A 4-year-old boy with a short history of jaundice and hepatomegaly was studied by endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC). A large obstructing choledochal tumour was found at the level of cystic duct insertion and at surgery, a botryoid sarcoma was removed. Subsequent cytotoxic therapy was complicated by persistent dilatation of the extrahepatic bile ducts which necessitated eventual excision. There was no evidence of persistent tumour.
