Diagnostic and Therapeutic Challenges of Intrahepatic Biliary Cystadenoma and Cystadenocarcinoma: A Report of 10 Cases and Review of the Literature.

The objective of this study was to present our experience with intrahepatic biliary cystadenomas and cystadenocarcinomas in 10 patients surgically managed in our department. Intrahepatic biliary cystadenomas and cystadenocarcinomas are rare cystic tumors that are often misdiagnosed preoperatively as simple cysts or hydatid cysts. They recur after incomplete resection and entail a risk of malignant transformation to cystadenocarcinoma.
