胎盘部位滋养细胞肿瘤(placental site trophoblastic tumor,PSTT)是指源于中间型滋养细胞(intermediate trophoblasts,Its),来自胎盘种植部位的一种特殊类型的滋养细胞肿瘤(gestational trophoblastic disease,GTD),其病理形态及生物学行为与其他滋养细胞肿瘤有诸多不同。胎盘部位滋养细胞肿瘤(PSTT)临床较少见,患者多因闭经、流产、葡萄胎或足月妊娠后阴道不规则流血而就诊。Kurman等~([1])于1976年首次使用“胎盘部位假瘤”描述该病,认为该病是滋养细胞侵蚀特性的
Placental site trophoblastic tumor (PSTT) refers to a special type of gestational trophoblastic disease (GTD) originating from the placental growth site derived from the intermediate trophoblasts, Its Pathological and biological behavior and other trophoblastic tumors have many different. Placental trophoblastic tumor (PSTT) clinical less common, mostly due to amenorrhea, abortion, hydatidiform mole or irregular vaginal bleeding after full-term pregnancy and treatment. Kurman et al ~ ([1]) first described the disease in 1976 as “placental pseudotumor”, which is considered to be a trophoblastic characteristic
