Chorangioma and chorangiosis: An important placental sign of chronic fetal hypoxia.Acase report

Chorangioma and chorangiosis are incompletly understood and overlapping villous capillaıy lesions believed by some to be related to hypoxia.The incidence of both pathologies are significantly higher in congenital malformations, preeclampsia, IUGR,premature delivery and gestation at high altitudes. Chorangioma, one of the most frequent tumors is seen %1 of the fullterm pregnancy. In histopathological examination of placentas with chorangiomas are found chorangiosis in neighbor villous. %5 of the newborns hospitalized in neonatal intensive care unit,have chorangiosis. We presented a 27 years old primigravid with placental mass , placentomegaly and IUGR at 27 th gestational weeks by prenatal ultrasound screening. Color Doppler imaging was revealed 7x9cm avascular solid placental mass, probably chorangioma, and without any anomalies in the fetus. Chorangioma resolved during pregnancy and occured fetal hypoxia. In this reason,at 38 weeks of gestation, Caessarean section was performed, baby was 2100g weight. Histopathological examination of placenta was chorangioma, chorangiosis and hemorrhagic infarc. We suggest that placental examination are important for diagnosis and following up of villous capillary lesions and their unpredictable outcomes.
