A placental site nodule is a benign proliferation of intermediate trophoblasts from a previous gestation that failed to completely involute. It is a rare entity that is often asymptomatic and is usually found incidentally weeks or even years after the pregnancy. The most common location for placental site nodules is in the uterus within the endometrium and occasionally in the cervix, diagnosed by uterine curettings or hysterectomy. However, rare extrauterine cases have been documented and should be considered as a differential diagnosis when encountered in locations such as the fallopian tube. Here, we present a case of a 28-year-old woman with a history of spontaneous abortions who was found to have a placental site nodule of the fallopian tube after postpartum tubal ligation.
胎盘部位结节是既往妊娠中未完全退化的中间型滋养细胞的良性增殖。它是一种罕见的病变，通常无症状，常在妊娠数周甚至数年之后偶然发现。胎盘部位结节最常见于子宫内膜内的子宫，偶尔见于宫颈，通过刮宫或子宫切除确诊。然而，已有罕见的子宫外病例报道，当在输卵管等部位发现时应考虑作为鉴别诊断。在此，我们报告一例28岁有自然流产史的女性，在产后输卵管结扎术后发现输卵管有胎盘部位结节。
