子宮筋腫の術前診断でTLHを実施した低異型度内膜間質肉腫の1例

抄録

  Here, we present a case of low-grade endometrial stromal sarcoma that was diagnosed after total laparoscopic hysterectomy was performed for the preoperative diagnosis of leiomyoma. A 49-year-old woman (gravida 1, para 1), who presented with the primary complaints of anemia and dizziness, was referred to our hospital. Based on ultrasound and magnetic resonance imaging findings, we diagnosed degenerated leiomyoma. We performed total laparoscopic hysterectomy and morcellation. Histopathological findings revealed a highly cellular neoplasm composed of round and spindle cells that had invaded the myometrium. Tumor cells were CD10 positive. This led to the diagnosis of low-grade endometrial stromal sarcoma. After informed consent was obtained, we performed laparoscopic bilateral salpingo-oophorectomy. Gross dissemination was not noted, and the peritoneal cytology was negative. Follow-up after 10 months was favorable.
