Primary schwannomas of the lower gastrointestinal tract are very rare and usually benign in nature. However, if they are not surgically removed, malign degeneration can occur. We report a case of a 79-year-old woman who presented to our clinic with rectal bleeding and constipation. She underwent a lower gastrointestinal tract endoscopy. A mass subtotally obstructing the lumen of the sigmoid colon was seen and biopsies were taken. Histopathological examination indicated a suspicion of gastrointestinal tumour and the patient underwent sigmoid colon resection after preoperative evaluation by laboratory analysis, abdominal ultrasonography and CT. Her postoperative course was uneventful and she was discharged on the fifth day for outpatient control. The histopathology report revealed schwannoma of the sigmoid colon. This was a case of schwannoma of the sigmoid colon that was successfully treated with total resection.<\/jats:p>","DOI":"10.1136\/bcr-2014-208934","type":"journal-article","created":{"date-parts":[[2015,5,14]],"date-time":"2015-05-14T14:54:52Z","timestamp":1431615292000},"page":"bcr2014208934","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":11,"title":["Schwannoma of the sigmoid colon"],"prefix":"10.1136","volume":"2015","author":[{"given":"Tu\u011frul","family":"\u00c7ak\u0131r","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arif","family":"Aslaner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00fcjgan","family":"Yaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Umut r\u0131za","family":"G\u00fcnd\u00fcz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,5,14]]},"reference":[{"key":"2025042706184219000_2015.may14_1.bcr2014208934.1","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v1.i1.49"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.2","doi-asserted-by":"crossref","first-page":"5079","DOI":"10.3748\/wjg.v11.i32.5079","article-title":"Sigmoid schwannoma: a rare case","volume":"11","author":"Fotiadis","year":"2005","journal-title":"World J Gastroenterol"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.3","doi-asserted-by":"publisher","DOI":"10.1159\/000237736"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.4","doi-asserted-by":"publisher","DOI":"10.1159\/000214837"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(88)80518-5"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.6","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199309000-00004"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.7","doi-asserted-by":"crossref","first-page":"142781","DOI":"10.1155\/2011\/142781","article-title":"Cecal schwannoma: a rare cause of gastrointestinal bleeding in a young woman with review of literature","volume":"2011","author":"Kanneganti","year":"2011","journal-title":"Gastroenterol Res Pract"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.8","doi-asserted-by":"publisher","DOI":"10.1007\/s005350050191"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.9","doi-asserted-by":"publisher","DOI":"10.1007\/s00384-006-0264-9"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.10","doi-asserted-by":"publisher","DOI":"10.1177\/106689690201000201"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.11","doi-asserted-by":"publisher","DOI":"10.3322\/canjclin.20.4.228"},{"key":"2025042706184219000_2015.may14_1.bcr2014208934.12","first-page":"779","article-title":"Case report of schwannoma of the rectum\u2013clinical and pathological contribution","volume":"6","author":"Maciejewski","year":"2000","journal-title":"Med Sci Monit"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2014-208934","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T13:18:47Z","timestamp":1745759927000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2014-208934"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,5,14]]},"references-count":12,"alternative-id":["10.1136\/bcr-2014-208934"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2014-208934","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,5,14]]}}}
