INTRODUCTIONSmooth muscle tumours of uncertain malignant potential (STUMP) include a diverse range of uterine neoplasms that don’t fit the current histological definitions for either benign or malignant tumours. STUMP might represent an intermediate form between leiomyomas and leiomyosarcomas or could be an undetected low-grade leiomyosarcoma[1]. Among women who undergo hysterectomy or myomectomy for a suspected leiomyoma, only 0.01% are diagnosed with STUMP [2]. Because this condition is so rare and diagnostic criteria are inconsistent, determining its true prevalence is challenging [3]. Additionally, with limited data on the malignant potential of STUMP, managing the condition is controversial, especially for patients who wish to preserve their fertility.Patients with STUMP experience a diverse range of symptoms like abnormal uterine bleeding, pelvic pain, and lower abdominal pressure, which are similar to those of benign uterine myomas. However, symptoms may vary depending on the size of the uterine mass [4].Since STUMP and benign uterine myomas show similarity as per preoperative radiologic imaging and laboratory tests, differentiating between them without pathological confirmation prior to surgery is challenging and nearly impossible. Conventional surgical treatment for STUMP usually involves myomectomy or hysterectomy. In some cases, myomectomy might be an option for women who wish to preserve their fertility [5].In this case report, we describe an unusual case of STUMP presenting as a large uterine mass, initially suspected to be a benign uterine myoma pre-operatively.Top of FormBottom of FormTop of FormBottom of Form
