Successful pregnancy following conservative management of low-grade endometrial stromal sarcoma: A case report

摘要

It is uncommon that fertility is preserved in young nulliparous females with low-grade endometrial stromal sarcoma (ESS). Therefore, successful pregnancy following such conservative management has been rarely reported in previous literature. A 25-year-old female (gravida, 0; para, 0) underwent hysteroscopic surgery and was pathologically diagnosed with an endometrial stromal nodule. The patient underwent fertility-preserving local resection and uterine reconstruction, with a final pathological diagnosis of low-grade ESS. Endocrine therapy was then administered. Conservative management resulted in the complete remission of low-grade ESS. The patient naturally conceived and successfully delivered a healthy baby at 42 weeks' gestation by cesarean section, ~30 months following diagnosis with low-grade ESS. In conclusion, conservative management, including fertility-preserving local mass resection and endocrine therapy, can be effective for low-grade ESS and may yield a favorable outcome for young nulliparous females desiring fertility preservation.
