Three cases of intrahepatic biliary cystadenoma with mesenchymal stroma and one case of biliary cystadenocarcinoma are presented. Their immunohistochemical features and the surgical treatment are discussed together with a brief review of the literature. The benign cystadenomas stained positive for cytokeratin and CA 19-9 in the epithelium of the cyst wall. Mesenchymal stromal cells were strongly positive for a-SMA and moderately positive for desmin. The epithelium of the cystadenocarcinoma, however, was positive only for cytokeratin and the stroma only for a-SMA. Our findings indicate that biliary cystadenomas seem to be of primitive hepatobiliary origin. Furthermore, the malignant variant cystadenocarcinoma may loose its immunoreactivity for CA 19-9 and desmin.
