CT of the abdomen and pelvis showed free air in the abdomen and a gas-fluid filled cavity measuring 12\u00d76\u2005cm in the mid-pelvis with possible fistulation that was suspicious for malignancy. A 10\u00d712\u2005cm ruptured dermoid cyst was found intraoperatively, which was adherent to the bowel wall. Bulky lymph nodes were also appreciated. The surgeon suspected a metastatic malignant teratoma, and a Hartmann's procedure, total abdominal hysterectomy and bilateral salpingoopherectomy were performed with clearance of the para-aortic lymph nodes. Subsequent histological analysis revealed a squamous cell carcinoma arising from an ovarian malignant teratoma. The patient went on to have carboplatin and paclitaxel chemotherapy and is alive at 6\u2005months follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2014-208472","type":"journal-article","created":{"date-parts":[[2015,5,2]],"date-time":"2015-05-02T07:30:07Z","timestamp":1430551807000},"page":"bcr2014208472","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Squamous cell carcinoma arising in a mature cystic teratoma invading the sigmoid colon: a rare presentation"],"prefix":"10.1136","volume":"2015","author":[{"given":"Alena Talia","family":"Gooneratne","sequence":"first","affiliation":[{"name":"Maidstone and Tunbridge Wells NHS Trust, Maidstone, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander Owen","family":"James","sequence":"additional","affiliation":[{"name":"Maidstone and Tunbridge Wells NHS Trust, Maidstone, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jyoti","family":"Gupta","sequence":"additional","affiliation":[{"name":"Maidstone and Tunbridge Wells NHS Trust, Maidstone, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasser","family":"Abdulaal","sequence":"additional","affiliation":[{"name":"Tunbridge Wells Hospital, Tunbridge Wells, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,5,2]]},"reference":[{"key":"2025082700584506000_2015.may02_1.bcr2014208472.1","doi-asserted-by":"publisher","DOI":"10.1006\/gyno.1996.0337"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0090-8258(03)00135-5"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.3","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(08)70306-1"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.4","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(19980601)82:11<2249::AID-CNCR21>3.0.CO;2-T"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.5","first-page":"521","article-title":"Squamous cell carcinoma arising in mature cystic teratoma (dermoid cyst)\u2013a rare presentation","volume":"63","author":"Chaudry","year":"2013","journal-title":"J Pak Med Assoc"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.6","first-page":"285","article-title":"Squamous cell carcinoma arising in a mature cystic ovarian teratoma with bladder invasion: a case report","volume":"11","author":"Badmos","year":"2011","journal-title":"Afr Health Sci"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2007.01478.x"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.8","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1438.2003.13312.x"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.9","doi-asserted-by":"publisher","DOI":"10.1159\/000293559"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.10","doi-asserted-by":"publisher","DOI":"10.1006\/gyno.1999.5602"},{"key":"2025082700584506000_2015.may02_1.bcr2014208472.11","doi-asserted-by":"publisher","DOI":"10.1007\/s11604-010-0434-0"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-208472","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T07:58:53Z","timestamp":1756281533000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-208472"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,5,2]]},"references-count":11,"alternative-id":["10.1136\/bcr-2014-208472"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-208472","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,5,2]]}}}
