TY - JOUR AB - Low‑grade endometrial stromal sarcoma (LG‑ESS) is a rare tumor that mostly occurs in perimenopausal women. Treatment with total hysterectomy and bilateral salpingo‑oophorectomy is recommended, although fertility preservation or ovarian preservation may be considered in younger patients. The present study reports a case of LG‑ESS in a young woman diagnosed after resection of endometrial polyp‑like lesions. A 26‑year‑old nulligravid woman was referred to our hospital after being diagnosed with endometrial polyps. Hysteroscopic endometrial polypectomy was performed twice, and LG‑ESS was suspected on postoperative pathological examination. Magnetic resonance imaging revealed a tumor 5‑cm in diameter on the right side of the uterus. In light of the young age of the patient, tumorectomy was first performed, and postoperative pathological diagnosis was LG‑ESS with the positive resection margin. After thorough discussion with the patient about fertility preservation and recurrence risk, a total abdominal hysterectomy and ovarian preservation was performed. Medroxyprogesterone therapy was performed postoperatively and no recurrence was observed for 2 years.
