title: Coexistent Chorangioma and Hepatic Adenoma in One Twin Placenta: A Case Report and Review of the Literature.
abstract: Primary nontrophoblastic tumors of a placenta are very uncommon, with the majority being of vascular origin, such as chorangiomas and chorangiomatosis. Rare examples of tumor-like collections of liver tissue, morphologically consistent with hepatocellular adenomas, have been reported. We report the co-occurrence of a chorangioma and hepatic adenoma as a grossly single lesion on the fetal surface of a diamniotic dichorionic twin placenta.
