部分性水泡状胎块及流产绒毛水泡样变性临床与病理鉴别

Clinical and Pathological Identification of Partial Mole and Hydropic Abortion

分析部分性水泡状胎块(简称胎块)72例及流产绒毛水样变性(简称变性)31例。结果:平均发病年龄胎块(31.14)早于变性(34.47);胎块的子宫大于停经月份(9/27),变性的子宫无大于停经月份者,子宫排空后HCG水平回复至正常平均时间,胎块为12.99d,变性为5.56d。病理所见:以水肿绒毛占全部绒毛1/3为准,胎块超过1/3的有57例(57/72),变性的31例均为1/3;胎块均有中央池,变性则均无中央池;胎块7例有港湾,90％有扇形绒毛为其病理特征。

Seventy-two cases of partial mole and thirty-one cases of hydropic abortion were analyzed. Results: The onset of partial mole is about 3 years eareier than that of hydropic abortion(mean age 31.14:34.47). The size of the uterus is larger than what is expected from menolipsis in partial mole (9/72), but not in hydropic abortion. The time interval required for the level of HCG to decrease to normal after evaculation was 12.99 days in partial mole and 5.56 days in hydropic abortion. Pathologi cally: Over 1/3 of the villi were edematous in most cases of parital mole(57/72), but none with more than 1/3 such villi in hydropic abortion. The formation of well demarcated central cisterns appeared in all cases of partial mole, but none in abortion. Partial. mole is characterized by fan-shaped villi in nearly 90％ of cases, and a gulf-like invagination into the villous stroma was found in 7 cases.
