Biliary mucinous cystadenoma: A review of the literature

Abstract

Biliary mucinous cystadenomas are cystic neoplasms com-monly mistaken for simple cysts. They are rare and generally benign tumors, often incidentally found on imaging and during unrelated surgical interventions. They tend to be slow growing though may reach symptomatic dimensions. Mis-diagnosis of biliary mucinous cystadenomas may have seri-ous consequences secondary to their potential for malignant transformation into biliary mucinous cystadenocarcinomas. Here, we review the epidemiology, etiology, pathology, diag-nostic modalities, histology, and available treatment methods for mucinous cystadenomas reported in current literature.
