Only three cases of ovarian chondrosarcoma have been reported in the literature, and almost all of these were components of ovarian teratomas. Herein, we report the clinicopathological characteristics of an ovarian chondrosarcoma in a 68\u2010year\u2010old woman who had previously undergone total hysterectomy. She had no subjective symptoms, and the tumor was unexpectedly found by further examination of osteoarthritis of the hip joint. Preoperative magnetic resonance imaging revealed curious findings of a lobulated high\u2010intensity component with a leaf\u2010vein\u2010like low\u2010intensity component. Computed tomography revealed irregularly distributed ossification extending to the entire tumor. Preoperative levels of CA125, CA19\u20109, carcinoembryonic antigen, \u03b1\u2010fetoprotein, and lactic dehydrogenase were all within normal limits. Macroscopic findings of the surgically resected tumor and pathologic findings revealed no teratoma component in the tumor. Finally, we diagnosed the tumor as a primary chondrosarcoma of the ovary.<\/jats:p>","DOI":"10.1111\/jog.16250","type":"journal-article","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T02:48:36Z","timestamp":1740365316000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Primary chondrosarcoma of the ovary"],"prefix":"10.1111","volume":"51","author":[{"given":"Yukiko","family":"Matsuzawa","sequence":"first","affiliation":[{"name":"Division of Obstetrics and Gynecology Tohoku Medical and Pharmaceutical University  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2435-5513","authenticated-orcid":false,"given":"Hiroki","family":"Kurosawa","sequence":"additional","affiliation":[{"name":"Division of Obstetrics and Gynecology Tohoku Medical and Pharmaceutical University  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Murakami","sequence":"additional","affiliation":[{"name":"Division of Pathology Tohoku Medical and Pharmaceutical University  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsumasa","family":"Osakabe","sequence":"additional","affiliation":[{"name":"Department of Molecular Diagnostic Pathology Iwate Medical University School of Medicine  Morioka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-0873-2924","authenticated-orcid":false,"given":"Yoh","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Division of Obstetrics and Gynecology Tohoku Medical and Pharmaceutical University  Sendai Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,23]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics12030643"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1447-0756.2011.01559.x"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1981.tb01791.x"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/PGP.0b013e318211f56e"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.5653\/cerm.2022.05372"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(78)80057-4"},{"key":"e_1_2_8_8_1","first-page":"113","article-title":"Ovarian ossification associated with endometriosis","volume":"34","author":"Shaco\u2010Levy R","year":"2007","journal-title":"Clin Exp Obstet Gynecol"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(95)90661-4"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13048-023-01268-1"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1447-0756.2011.01833.x"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10147-008-0807-x"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-008-0595-6"},{"key":"e_1_2_8_14_1","first-page":"2356","article-title":"Non\u2010teratomatous ossification of the ovary, a rare entity: case report and review of the literature","volume":"13","author":"Yu EH","year":"2020","journal-title":"Int J Clin Exp Pathol"}],"container-title":["Journal of Obstetrics and Gynaecology Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.16250","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T01:51:37Z","timestamp":1741744297000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1111\/jog.16250"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,2]]},"references-count":13,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025,2]]}},"alternative-id":["10.1111\/jog.16250"],"URL":"https:\/\/doi.org\/10.1111\/jog.16250","archive":["Portico"],"relation":{},"ISSN":["1341-8076","1447-0756"],"issn-type":[{"type":"print","value":"1341-8076"},{"type":"electronic","value":"1447-0756"}],"subject":[],"published":{"date-parts":[[2025,2]]},"assertion":[{"value":"2024-08-21","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-02-10","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-02-23","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e16250"}}
