We report a case of schwannoma of the ascending colon that was resected laparoscopically. A 64-year-old woman was referred to our hospital by her local clinic for further evaluation and management of a submucosal tumor of the ascending colon. A definitive preoperative diagnosis could not be reached despite examinations. Gastrointestinal stromal tumor, leiomyoma and lymphoma were the differential diagnoses. We performed a laparoscopic right hemicolectomy with D2 lymph node dissection. Histological findings with hematoxylin-eosin staining revealed spindle-like tumor cells, and immunohistochemical analysis showed that the tumor was positive for S-100 but negative for c-kit, CD34, smooth muscle actin and desmin, with a Ki-67 index of &lt;5%. Thus, the diagnosis in this case was benign schwannoma of the ascending colon.<\/jats:p>","DOI":"10.1159\/000373882","type":"journal-article","created":{"date-parts":[[2015,6,17]],"date-time":"2015-06-17T22:36:37Z","timestamp":1434580597000},"page":"15-19","source":"Crossref","is-referenced-by-count":8,"title":["Laparoscopic Resection of Schwannoma of the Ascending Colon"],"prefix":"10.1159","volume":"9","author":[{"given":"Yoshihiko","family":"Tashiro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumio","family":"Matsumoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keiko","family":"Iwama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ai","family":"Shimazu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sei","family":"Matsumori","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeo","family":"Nohara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyoshi","family":"Miura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiko","family":"Takei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Namekata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaru","family":"Takase","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Motoi","family":"Okada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidenori","family":"Tsumura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2015,1,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(88)80518-5"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02239444"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200107000-00002"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1007\/s005950170060"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159\/000237736"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2002.120323"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00535-004-1383-0"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159\/000214837"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1007\/s00384-006-0264-9"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(04)15947-3"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa032651"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(02)09290-5"}],"container-title":["Case Reports in Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/373882","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/373882","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:36:09Z","timestamp":1745429769000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000373882"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,1,16]]},"references-count":12,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2015,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000373882","archive":["Portico"],"relation":{},"ISSN":["1662-0631"],"issn-type":[{"type":"electronic","value":"1662-0631"}],"subject":[],"published":{"date-parts":[[2015,1,16]]}}}
