[Placental chorioangioma. Two cases and review of the literature].

Two cases of placental chorioangiomas were discovered, one echographically after in utero death at mid-term pregnancy and the second during the neonatal period associated with acute hydramniosis and a single umbilical artery. At 8 months, the new-born was in good health after persistent cholestasis at birth. A review of the literature of the macroscopic, histologic, echographic characteristics and the foetal-maternal complications of chorioangiomas revealed few cases of in utero death, especially so early in term.
