Biliary cystadenocarcinoma (BCAC) is a very rare malignant cystic neoplasm. Some authors think this particular neoplasm was conversion of biliary cystadenoma over several years of evolution. In the majority of the cases, it habitually occurs in the liver parenchyma (intrahepatic cystadenocarcinoma); sometimes can be observed extrahepatic biliary origin3,4,6,7,8,10,11 extrahepatic biliary cystad...

background: patients with malignant obstruction of the biliary tract suffer from progressive jaundice and purities, and if the obstruction is not relieved they will die from cholangitis, septicaemia or liver failure. the correct choice between many operative and non-operative procedures available to relive jaundice is not yet determined. unresectable disease (perihilar cholangiocarcinoma) found...

Background The objective of this study was to investigate the incidence, demographics, tumor characteristics, treatment, and survival of patients with hilar cholangiocarcinoma. Methods Data on Klatskin tumors between 2004 and 2013 was extracted from the Surveillance, Epidemiology and End Results Registry. The epidemiology of these tumors was then analyzed. Results A total of 254 patients wi...

We report a case in an inoperable patient with type IV Klatskin tumor treated by the use of a novel, two piece, Y-configured self-expandable metallic stent (SEMS) combined with two (125)I seed strands via bilateral approach. The placement of the Y-shaped SEMS was successful and resulted in adequate biliary drainage. After 2 months of intraluminal brachytherapy (ILBT), both (125)I seed strands a...

Neurilemmoma rarely develops in the biliary tree. Here, we report a 39-year-old Iranian woman with neurilemmoma in the extrahepatic bile duct presenting with progressively deepening jaundice. On the basis of clinical and radiological features, this tumor was initially suspected as Klatskin tumor. Histologically, the tumor was a typical neurilemmoma. Immunostaining showed that tumor cells were s...
