They often pose a diagnostic challenge, particularly in postmenopausal women, as they can clinically and radiologically mimic ovarian malignancy. Histopathological confirmation remains essential, and complete surgical excision yields an excellent prognosis. To our knowledge, the present report represents one of the few reported cases of primary ovarian leiomyoma in a postmenopausal woman from Sub\u2010Saharan Africa. We report a case of primary ovarian leiomyoma in a 78\u2010year\u2010old postmenopausal woman (P2L2) who presented to a tertiary referral center in Northern Tanzania with a 1\u2010year history of gradual onset abdominal pain and distension. She had a 20\u2010year smoking history and long\u2010term use of combined oral contraceptive pills. Laboratory findings showed mild anemia (hemoglobin 9.2\u2009g\/dL) with normal serum CA\u2010125 (20\u2009U\/mL) and carcinoembryonic antigen (3\u2009ng\/mL). Physical examination revealed abdominal distension, tenderness in the right lower quadrant, and a palpable pelvic mass with full vaginal fornices. Contrast\u2010enhanced computed tomography demonstrated a large 15\u2009\u00d7\u200911\u2009\u00d7\u200916\u2009cm multiloculated cystic mass with internal septations arising from the right adnexa, extending to the subhepatic region, causing significant mass effect on adjacent structures including the right kidney and bowel loops. Multiple uterine fibroids were also noted. She underwent a total abdominal hysterectomy (TAH) with bilateral salpingo\u2010oophorectomy (BSO). Histopathological examination revealed a well\u2010circumscribed tumor comprised of smooth muscle with degenerative change, bundles of interlacing fascicles without atypia. Immunohistochemical analysis demonstrated strong positivity for smooth muscle actin (SMA) and desmin in the tumor cells. Overall, the findings are consistent with a diagnosis of ovarian leiomyoma with degenerative changes. The postoperative period was uneventful, and the patient was discharged three days postoperatively. At regular follow\u2010up, there has been no evidence of recurrence.<\/jats:p>","DOI":"10.1002\/ccr3.73385","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T04:27:01Z","timestamp":1787545621000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Giant
