Several cases of endoscopic resection of colorectal leiomyomas have been described. However, conventional polypectomy of leiomyomas can result in perforation. To reduce the risk of perforation, submucosal injection can be performed before removal. We report a case of chronic sideropenic anaemia in a patient affected by leiomyoma of the sigmoid colon in which after complete endoscopic enucleation of the lesion we obtained the stable resolution of anaemia.<\/jats:p>","DOI":"10.1136\/bcr.11.2009.2455","type":"journal-article","created":{"date-parts":[[2011,2,2]],"date-time":"2011-02-02T09:49:56Z","timestamp":1296640196000},"page":"bcr1120092455","source":"Crossref","is-referenced-by-count":0,"title":["Obscure-occult bleeding: resolution of unexplained chronic sideropenic anaemia by colonoscopic removal of a colonic leiomyoma"],"prefix":"10.1136","volume":"2011","author":[{"given":"Riccardo","family":"Urgesi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfredo","family":"Pastorelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Costantino","family":"Zampaletta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Masini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giorgio","family":"Pelecca","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Faggiani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcello","family":"Anti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2011,2,2]]},"reference":[{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.1","first-page":"784","article-title":"Smooth muscle tumors of the gastrointestinal tract and retroperitoneal tissues","volume":"73","author":"Golden","year":"1941","journal-title":"Surg Gynecol Obstet"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01296125"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.3","doi-asserted-by":"publisher","DOI":"10.1097\/00004836-199207000-00014"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.4","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5107(79)73388-8"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.5","first-page":"149","article-title":"Leiomyoma of the rectum","volume":"70","author":"Sasaki","year":"1985","journal-title":"Int Surg"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.6","doi-asserted-by":"crossref","first-page":"87","DOI":"10.2298\/ACI0601087J","article-title":"Endoscopic removal of pedunculated leiomyoma of the sigmoid colon (case report and literature review of dignostic and treatment options)","volume":"53","author":"Jovanovic","year":"2006","journal-title":"Acta Chir Iugosl"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.7","first-page":"325","article-title":"Endoscopic removal of leiomyoma of the colon","volume":"3","author":"Chow","year":"1997","journal-title":"Hong Kong Med J"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.8","first-page":"213","article-title":"Colonic leiomyoma with huge ulceration","volume":"26","author":"Takeda","year":"2007","journal-title":"Indian J Gastroenterol"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.9","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197701)39:1<263::AID-CNCR2820390140>3.0.CO;2-B"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.10","first-page":"153","article-title":"Leiomyoma of intestine","volume":"66","author":"Murphy","year":"1973","journal-title":"J Ir Med Assoc"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.11","first-page":"39","article-title":"Endoscopic resection of a large colonic leiomyoma","volume":"25","author":"Lee","year":"2002","journal-title":"Chang Gung Med J"},{"key":"2025082703513739000_2011.jan29_1.bcr1120092455.12","first-page":"218","article-title":"Endoscopic resection of a pedunculated colonic leiomyoma resembling a hyperplastic polyp","volume":"37","author":"Park","year":"2008","journal-title":"Korean J Gastrointest Endosc"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.11.2009.2455","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T10:51:44Z","timestamp":1756291904000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.11.2009.2455"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":12,"alternative-id":["10.1136\/bcr.11.2009.2455"],"URL":"https:\/\/doi.org\/10.1136\/bcr.11.2009.2455","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2011]]}}}
