Abstract

Chorioangiomas are benign angiomas arising from chorionic tissue and they are the most common non-trophoblastic tumors of the placenta, as they are observed in 1% of all placentas examined. Most chorioangiomas are small and asymptomatic, often undetected during a prenatal ultrasound, and their clinical significance is still unknown. Large chorioangiomas, measuring more than 4-5 cm in diameter, can usually be detected prenatally by gray-scale or color Doppler sonography, and may be associated with maternal or fetal complications, such as preeclampsia, maternal mirror syndrome, preterm delivery, nonimmune fetal hydrops, fetal growth restriction and fetal demise. We herein describe the clinical-pathological features of a monocentric series of 30 placental chorioangiomas and discuss their clinical-pathological features and possible molecular mechanisms underlying their development.

胎盘绒毛血管瘤病例系列,临床指征为组织学检查。
绒毛血管瘤是由绒毛组织产生的良性血管瘤,是胎盘中最常见的非滋养细胞肿瘤,在所有受检胎盘中占 1%。大多数绒毛膜血管瘤较小且无症状,通常在产前超声检查中未被发现,其临床意义尚不清楚。大的绒毛膜血管瘤直径超过 4-5 厘米,通常可在产前通过灰阶或彩色多普勒超声检查发现,可能与母体或胎儿的并发症有关,如子痫前期、母体镜像综合征、早产、非免疫性胎儿水肿、胎儿生长受限和胎儿死亡。我们在此描述了 30 例胎盘绒毛膜血管瘤单中心系列的临床病理特征,并讨论了其临床病理特征及其可能的分子机制。
