Background/Aims:
To evaluate the phenomenon and the potential reasons for protrusion and growth of hepatobiliary cystadenoma into the extrahepatic bile ducts in our patients, accomplished by a review of the data regarding hepatobiliary cystadenomas published elsewhere.
Methodology:
In a retrospective open study conducted over the last eight years, five patients with hepatobiliary cystadenoma and one patient with hepatobiliary cystadenocarcinoma were operated on. All the patients were females aged between 25 to 61 years. Diagnostic procedures, laboratory, operative and histopathological findings and treatment were evaluated.
Results:
Most of our patients were found to have hepatobiliary cystadenoma located in the left surgical liver. In three out of five patients with HBC mesenchymal stroma was histologically detected. In two of the three, protrusion and growth into the extrahepatic bile ducts was found.
Conclusion:
Considering the pathogenesis, location and the morphology of HBC, the mesenchymal stroma may present the competent potential for intraductal progression of the tumor. Radical excision should be performed for successful treatment of hepatobiliary cystadenomas, because of the potential for reoccurrence.
