Endometrial stromal sarcoma diagnosed after hysteroscopic endometrial resection

Endometrial ablation and resection is now common therapy for dysfunctional uterine bleeding that is unresponsive to conservative management. Opponents argue that it may predispose patients to potentially hazardous malignancies of the uterus. In our patient, endometrial resection was performed to treat menorrhagia after a negative workup. Pathologic interpretation of the resected tissue showed a low-grade stromal sarcoma of the endometrium. The woman underwent definitive treatment, which included total abdominal hysterectomy, and has remained recurrence free over the past 3 years. Although rare, uterine malignancies have been documented after hysteroscopic management of menorrhagia. It is suggested that intraoperative endometrial resection or tissue sampling be done to prevent or diagnose endometrial hyperplasia and uterine malignancies.
