Imaging (ORADS 5) and markedly elevated CA-125 suggested advanced ovarian carcinoma. Despite receiving seven cycles of carboplatin\/paclitaxel chemotherapy for presumed primary peritoneal carcinoma, the mass and ascites persisted. Following laparotomy and left salpingo-oophorectomy, histopathology confirmed benign struma ovarii without peritoneal carcinomatosis. Postoperatively, ascites resolved and CA-125 normalized. The patient remained well with no recurrence at 14-month follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case underscores the critical importance of considering struma ovarii in the differential diagnosis of a complex ovarian mass, even when clinical features and tumor markers strongly suggest malignancy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/omcr\/omag124","type":"journal-article","created":{"date-parts":[[2026,7,12]],"date-time":"2026-07-12T22:43:57Z","timestamp":1783896237000},"source":"Crossref","is-referenced-by-count":0,"title":["Benign\n                    <i>struma ovarii<\/i>\n                    mimicking ovarian cancer in an afghan woman: an unusual case report and literature review"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6494-5773","authenticated-orcid":false,"given":"Maryam","family":"Yousefi","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, School of Medicine, Clinical Research Development Unit, Shahid Beheshti Hospital, Qom university of Medical Sciences , Qom ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elham Sadat","family":"Banimostafavi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Gastroenterology and Hepatology Diseases Research Center, Interdisciplinary Research Committee, Shahid Beheshti Hospital, Qom University of Medical Sciences , Qom ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahdiieh","family":"Ghoddoosi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kamkar-Arabnia Hospital, Qom University of Medical Sciences , Qom ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,7,12]]},"reference":[{"key":"2026072710484332400_ref1","doi-asserted-by":"publisher","first-page":"455","DOI":"10.1007\/s12022-023-09789-7","article-title":"Neoplasms in Struma Ovarii: a review","volume":"34","author":"Tondi Resta","year":"2023","journal-title":"Endocr Pathol"},{"key":"2026072710484332400_ref2","doi-asserted-by":"publisher","first-page":"14","DOI":"10.1186\/s13044-022-00132-6","article-title":"Management of malignant struma ovarii: is aggressive therapy justified?
