Hemangioendothelioma of the Hepatobiliary System

Kaposiform hemangioendothelioma of the choledochus

“…Involvement of the choledochus by hemangioendothelioma (not mentioned as kaposiform) has been reported in 2 cases [9,10]. They were unlikely KHE according to the description and posted microscopic photographs, so the present case is likely the first report of choledochal involvement by KHE.…”

A Rare Cause for Extrahepatic Biliary Tract Obstruction: Juvenile Hepatic Hilar Hemangioma

“…In conclusion, obstructive jaundice due to extrahepatic compression of the bile duct system can be caused by different tumors. [1][2][3] Our report describes the rare and previously not described entity of juvenile hemangioma. This etiology of extrahepatic bile duct obstruction should be suspected as differential diagnosis in those cases where extrahepatic biliary atresia or inspissated bile syndrome can be ruled out.…”

“…However, those tumors causing obstructive jaundice have been rarely reported in the literature so far. [1][2][3] This unique case highlights that extrahepatic bile duct obstruction can be caused by a juvenile hemangioma atypically located in the hepatic hilum. As in general, therapeutic options include percutaneous transhepatic drainage as well as bypass surgery or biliaryenteric anastomosis.…”
