Challenges Associated with Smooth Muscle Tumor of Uncertain Malignant Potential (STUMP) Management-A Case Report with Comprehensive Literature Review.

Smooth Muscle Tumor of Uncertain Malignant Potential (STUMP) is a poorly studied neoplasm that does not fulfill the definition of either leiomyoma or leiomyosarcoma. STUMP symptoms are indistinguishable from those of benign lesions; it has no specific biochemical markers or ultrasound presentations. The management of this type of tumor is particularly challenging due to significant heterogeneity in its behavior and the lack of clear guidelines; moreover, the lesion may recur after excision. : We report on a case of a 42-year-old patient diagnosed with a STUMP. The preliminary diagnosis was a submucous leiomyoma, which was removed hysteroscopically due to menorrhagia resulting in anemia. The histopathological examination of the resected myoma pointed to the diagnosis of STUMP. The hysterectomy was performed as the patient had completed her reproductive plans. There were no complications. The patient is currently recurrence-free after a 9-month follow-up. : The care of a patient diagnosed with STUMP requires a personalized approach and the cooperation of various medical disciplines, including molecular diagnostics, imaging techniques, and minimally invasive surgery. Management of STUMP must consider the patient's plans for childbearing. All cases of tumors with "uncertain malignant potential" are a challenge in the context of patient-physician communication.
