Uterine smooth muscle tumors of uncertain malignant potential (STUMP): A case report.

INTRODUCTION

Uterine smooth muscle tumors of uncertain malignant potential (STUMP) are extremely rare, defined as a uterine smooth muscle tumors that cannot be diagnosed as benign or malignant and does not satisfy all the criteria for leiomyosarcoma or leiomyoma.

CASE REPRESENTATION: A 48-year-old woman who presented with a history of heavy menstrual bleeding and pelvic pain. Physical examination revealed an enlarged uterus. Ultrasonography showed lobular and enlarged uterus containing multiples leiomyomas. A subtotal hysterectomy was performed. A Pathological analysis revealed a uterine mass diagnosed as a smooth muscle tumor of uncertain malignant.

DISCUSSION: Uterine STUMPs are rare and are commonly diagnosed by histopathological evaluation following myomectomy or hysterectomy. The most common clinical manifestations of uterine STUMP are the same as leiomyomas. Prognosis for the patient is unclear and there is a risk of recurrence with the tumors. However, considering their potential risk of recurrence and metastasis, it is advisable to maintain six-monthly controls for 5 years and then annual controls for 5 years more.

CONCLUSION

Due to the rarity of uterine STUMP, there are no specific guidelines for their treatment and control. The scientific literature needs to be constantly updated in order to identify masses suspected of malignancy before surgery and improve patient management and follow-up.
