Malignant transformation, most commonly to papillary thyroid carcinoma, occurs in 5%\u201310% of cases and represents an exceptionally rare entity with no established management consensus. We report a 40-year-old woman presenting with acute pelvic pain and a 13\u00a0cm heterogeneous left adnexal mass with elevated CA-125 (125\u00a0U\/ml). Emergency laparotomy with left salpingo-oophorectomy revealed a 1\u00a0cm papillary thyroid carcinoma arising within an 11\u00a0cm struma ovarii, without capsular or vascular invasion. Postoperative thyroid workup was normal. Despite multidisciplinary recommendations for completion thyroidectomy and contralateral adnexectomy, the patient declined further surgery, opting for clinical and biochemical surveillance alone. This case underscores the importance of managing malignant struma ovarii according to thyroid carcinoma protocols while respecting patient autonomy.<\/jats:p>","DOI":"10.1093\/jscr\/rjag264","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T11:37:01Z","timestamp":1774957021000},"source":"Crossref","is-referenced-by-count":0,"title":["Malignant
