Cystandenoma and Primary Cystadenocarcinoma of the Liver.

Primary cystic neoplasia of the liver is rare. We report a cystadenoma with mesenchymal stroma (CMS) and a cystadenocarcinoma, and make a review of literature with particular reference to their histogenesis. The CMS has many similarities to the ovarian mucinous cystadenoma; occurring almost exlusively in female, being lined by mucus-secreting epithelial cells, and containing dense ovarian-like stroma. These features suggest that CMS may arise from the ectopic ovarian tissue within the liver. Cystadenocarcinoma may have its origin in CMS or cystadenoma without mesenchymal stroma of CMS. Cholangiocarcinoma arising from the congenital hepatic cysts can be differentiated only when it contains benign epithelia.
