Background: Smooth muscle cell tumor of uncertain malignant potential is a rare tumor. By reporting a case report, our study aims to define this tumor, its therapeutic management, and its prognosis.
Case report: Our patient is a multiparous 46 years-old patient with chronic pelvic pain and no pathological medical history. Her pelvic ultrasonography showed an aspect of a 64 mm uterine fibroid. She underwent a myomectomy. The anatomopathological study showed a smooth muscle cell tumor of uncertain malignant potential. A total hysterectomy with bilateral adnexectomy was performed. No signs of recurrence were noted during surveillance.
Conclusion: Smooth muscle cell tumor of uncertain malignant potential are heterogeneous with no clinical nor radiological specific signs. The treatment is mainly surgical with hysterectomy or myomectomy if fertility preservation is desired. The risk of recurrence is always present and can occur after several years hence the importance of prolonged monitoring.
Key words: Smooth muscle cell tumor of uncertain malignant potential, uterine STUMP, myoma, recurrence
