Uterine smooth muscle tumor of uncertain malignant potential: a case report.

Uterine smooth muscle tumor of uncertain malignant potential (STUMP) is a rare borderline smooth muscle tumor. This paper reports a case of STUMP and discusses its clinical characteristics, diagnostic challenges, and treatment strategies in combination with relevant literature. The patient was a young female who presented with menorrhagia and severe anemia. Pelvic ultrasound revealed a large mass in the uterus, which was suspected to be a uterine leiomyoma. Surgical resection of the mass was subsequently performed, and postoperative pathological examination confirmed the diagnosis of STUMP. The risk factors and biological mechanisms underlying the development of STUMP remain poorly understood. The tumor lacks specific clinical and imaging features, making diagnosis primarily dependent on histopathological evaluation. Surgery is the mainstay of treatment, and close follow-up is recommended postoperatively.
