The report describes a 23-year-old woman with progressive lower abdominal pain, urinary frequency, constipation, and dysuria for two months. Examination identified a large, immobile mass, and MRI demonstrated a sizable abdominopelvic lesion with subtle hypermetabolism on fluorodeoxyglucose-PET, suggesting a low-grade stromal process. Exploratory surgery found a mass arising from the right broad ligament and enabled total excision. Histopathology showed features consistent with stromal tumor of unknown malignant potential (STUMP), and follow-up at six months showed no metastasis or recurrence.

Here, we present the case of a 23-year-old female who complained of pain in the lower abdomen, urinary frequency, constipation, and dysuria for the last two months. The examination showed a solid, immobile lower abdominal mass measuring approximately 20 × 25 cm. MRI revealed a clearcut abdominopelvic lesion measuring 7.9 × 19.7 × 30.4 cm, and fluorodeoxyglucose-positron emission tomography depicted subtle hypermetabolic activity, indicative of a low-grade stromal lesion. During an exploratory laparotomy, a large mass arising on the right broad ligament was noted, and total excision was performed. Histopathology revealed a smooth muscle tumor with mild-to-moderate atypia, low mitotic activity, and absence of coagulative necrosis, which was consistent with a diagnosis of stromal tumor of unknown malignant potential (STUMP) . The course after surgery was uneventful, and at the six-month follow-up, the patient did not show any metastasis or recurrence. This case described the diagnostic difficulties of extrauterine STUMP and the significance of histopathological verification and regular followup surveillance.  \nCategories: Obstetrics/Gynecology, General Surgery, Oncology  \nKeywords: abdominopelvic mass, malignancy, stromal tumor of unknown malignant potential (stump), tumor, uterine smooth muscle tumor  \nIntroduction  \nGynecological pelvic masses in women of reproductive age need early investigation to determine the benign processes and rare tumor occurrences [1,2] . Uterine smooth muscle tumors can be seen in women aged between 30 and 50 years, with benign leiomyoma being the most common. A minor group of tumors has atypical histological characteristics and is known as smooth muscle tumor of uncertain malignant potential (STUMP) [3] . Recurrence rates are reported to range approximately 7-20% with infrequent development of leiomyosarcoma during follow-up, highlighting the need for long-term monitoring [3-6]. The preoperative diagnosis is also troublesome, as ultrasonography and MRI usually present vague appearances and can be similar to leiomyoma [3] . Hence, the practice is based on imaging as an indicator of the extent of the tumor and the involvement of the organs, and the conclusive diagnosis is confirmed with the help of postoperative histopathological examination. A tumor is a STUMP when it does not meet certain parameters to diagnose leiomyosarcoma, namely, in terms of mitotic rate, cell atypia, and the absence or presence of coagulative tumor cell necrosis (CTCN) [7] . No standard management guidelines apply to STUMP, but complete surgical excision is usually advised, with hysterectomy being the preferred option in patients who have already given birth and myomectomy in younger women who desire to preserve fertility [5,6] . This case of a broad ligament STUMP in an unusual location in a young female at the age of 23 years presents diagnostic uncertainties, pointing to the need to consider surgical decision-making in young individuals and the significance of organized postoperative monitoring.  \nCase Presentation  \nA 23-year-old unmarried female presented with a history of intermittent","cbCaiePzPc0HIv4Q","https://ap.wps.com/l/cbCaiePzPc0HIv4Q","pdf",7602705,"English","# Abstract\n# Introduction\n# Case Presentation\n## Imaging and diagnostic workup\n# How to cite this article","[{\"question\":\"Who is described in the case report and what symptoms did they have?\",\"answer\":\"A 23-year-old female presented with intermittent dull lower abdominal pain, urinary frequency, dysuria, constipation, and difficulty passing flatus.
