Congenital vascular malformation of the uterus in a stillborn: a case report.

A case of a rare condition of uterine vascular malformation is reported in a stillborn fetus. No other vascular lesion was identified in the fetus during autopsy. The finding of a uterine vascular malformation in a stillborn fetus confirms the congenital nature of some uterine vascular lesions. Congenital uterine vascular malformations warrant clinical and pathomorphological differentiation from acquired arteriovenous fistulas of the uterus.
