妊娠滋养细胞肿瘤以往均指侵蚀性葡萄胎和绒毛膜癌,自从对滋养细胞的分化进一步认识后,已知除细胞滋养细胞和合体滋养细胞外还有中间型滋养细胞。中间型滋养细胞中的种植部位中间型滋养细胞,部分可形成胎盘部位的滋养细胞肿瘤(PSTT);绒毛膜型中间型滋养细胞,少数可形成上皮型滋 Gestational trophoblastic tumors have traditionally been both invasive hydatidiform mole and choriocarcinoma. Since the further understanding of the differentiation of trophoblast cells, it is known that in addition to cytotrophoblasts and syncytiotrophoblasts, there are also intermediate trophoblasts. Intermediate trophoblast cells in the middle part of the trophoblastic part of the placental part of the formation of trophoblastic tumor (PSTT); chorionic mesenchymal cells, a few can form epithelial zygotes
