Multilocular cystadenoma of the liver with mural nodules.

ABSTRACT

Hepatobiliary cystadenoma, characterised by the interposition of a mesenchymal stroma beneath the epithelium and the connective tissue layer, is a tumor described exclusively in women. These tumors have a potential for malignant transformation. Complete surgical excision is mandatory. We report a case cystadenoma with mesenchymal stroma (CMS), with mural nodules in the cyst wall, similar to those described in ovarian mucinous cystadenoma.
