They occasionally present as incidental sessile polyps during colonoscopy. A 55-year-old asymptomatic female patient with a medical history of multiple sclerosis presented for a screening colonoscopy. A 5\u2009mm low-risk tubular adenoma was noted in the caecum, and a second 5\u2009mm polyp was found in the ascending colon. Histopathology of the ascending colon polyp showed proliferation of spindle cells without ganglion cells in the lamina propria. Immunohistochemical findings are compatible with an MSCH. Surveillance colonoscopy was scheduled in 5\u2009years based on the presence of a single low-risk tubular adenoma.<\/jats:p>","DOI":"10.1136\/bcr-2018-224931","type":"journal-article","created":{"date-parts":[[2018,9,21]],"date-time":"2018-09-21T23:57:24Z","timestamp":1537574244000},"page":"bcr-2018-224931","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":12,"title":["Case of colonic mucosal Schwann cell hamartoma and review of literature on unusual colonic polyps"],"prefix":"10.1136","volume":"2018","author":[{"given":"JayaKrishna","family":"Chintanaboina","sequence":"first","affiliation":[{"name":"Penn State Milton S Hershey Medical Center, Hershey, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kofi","family":"Clarke","sequence":"additional","affiliation":[{"name":"Penn State Milton S Hershey Medical Center, Hershey, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,9,21]]},"reference":[{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.1","doi-asserted-by":"crossref","first-page":"187","DOI":"10.4132\/jptm.2016.07.02","article-title":"Mucosal schwann cell hamartoma in colorectal mucosa: a rare benign lesion that resembles gastrointestinal neuroma","volume":"51","author":"Han","year":"2017","journal-title":"J Pathol Transl Med"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.2","doi-asserted-by":"publisher","DOI":"10.1097\/01.MP.0000062860.60390.C7"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199903183401107"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.4","doi-asserted-by":"crossref","first-page":"134","DOI":"10.5858\/2008-0083-RSR2.1","article-title":"Gastrointestinal stromal tumors: a review of the literature","volume":"134","author":"Laurini","year":"2010","journal-title":"Arch Pathol Lab Med"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.5","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.3880417"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.6","doi-asserted-by":"publisher","DOI":"10.1097\/GIM.0b013e318216cc6d"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.7","doi-asserted-by":"crossref","first-page":"21663626","DOI":"10.1186\/1471-230X-11-68","article-title":"Schwann cell hamartoma: case report","volume":"11","author":"Rocco","year":"2011","journal-title":"BMC Gastroenterol"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.2006.02370.x"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.9","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e31818dd6ca"},{"key":"2025082803081389000_2018.sep21_1.bcr-2018-224931.10","first-page":"183","article-title":"Mucosal schwann cell hamartoma of the colon in a patient with ulcerative colitis","volume":"9","author":"Neis","year":"2013","journal-title":"Gastroenterol Hepatol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-224931","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:08:22Z","timestamp":1756375702000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-224931"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,9,21]]},"references-count":10,"alternative-id":["10.1136\/bcr-2018-224931"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-224931","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2018,9,21]]}}}
