An elderly male was found to have a left colon mass on CT scan and colonoscopy with pathology of fibrotic tissue. A laparoscopic-assisted left hemi-colectomy with primary anastomosis was performed. Pathology demonstrated spindle cell neoplasm arranged in short fascicles that were strongly and diffusely positive for S100. An elderly female was found to have a submucosal lesion on surveillance colonoscopy in the proximal transverse colon. Biopsy with jumbo forceps revealed spindle cell neoplasm positive for S100. Patient underwent an uncomplicated limited non-oncologic segmental transverse colectomy. We report only the ninth case of left and sixth in the transverse colon described in the literature. As is true for other mesenchymal tumors, mucosal biopsy is usually inconclusive and deep biopsy or submucosal resection is required, making pre-operative surgical decision difficult.<\/jats:p>","DOI":"10.1093\/jscr\/rjac438","type":"journal-article","created":{"date-parts":[[2023,12,30]],"date-time":"2023-12-30T08:10:55Z","timestamp":1703923855000},"source":"Crossref","is-referenced-by-count":0,"title":["Rare cases of colonic schwannomas"],"prefix":"10.1093","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2923-6573","authenticated-orcid":false,"given":"Victor","family":"Gazivoda","sequence":"first","affiliation":[{"name":"Maimonides Medical Center , Brooklyn, NY , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donghai","family":"Wang","sequence":"additional","affiliation":[{"name":"Yale University School of Medicine , New Haven, CT , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa","family":"Siddique","sequence":"additional","affiliation":[{"name":"Maimonides Medical Center , Brooklyn, NY , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiangying","family":"Zeng","sequence":"additional","affiliation":[{"name":"Maimonides Medical Center , Brooklyn, NY , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie E","family":"Robert","sequence":"additional","affiliation":[{"name":"Yale University School of Medicine , New Haven, CT , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haddon","family":"Pantel","sequence":"additional","affiliation":[{"name":"Yale University School of Medicine , New Haven, CT , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne","family":"Mongiu","sequence":"additional","affiliation":[{"name":"Yale University School of Medicine , New Haven, CT , United States"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,12,29]]},"reference":[{"key":"2023123007544716400_ref1","doi-asserted-by":"crossref","first-page":"116","DOI":"10.1159\/000214837","article-title":"A case of benign schwannoma of the transverse colon with granulation tissue","volume":"3","author":"Tsunoda","year":"2009","journal-title":"Case Rep Gastroenterol"},{"key":"2023123007544716400_ref2","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1186\/s12957-018-1427-1","article-title":"Schwannoma of the colon and rectum: a systematic literature review","volume":"16","author":"Bohlok","year":"2018","journal-title":"World J Surg Oncol"},{"key":"2023123007544716400_ref3","doi-asserted-by":"crossref","first-page":"178","DOI":"10.1111\/j.1758-5910.2011.00089.x","article-title":"Cecal schwannoma with laparoscopic wedge resection: report of a case","volume":"4","author":"Matsumoto","year":"2011","journal-title":"Asian J Endoscopic Surg"},{"key":"2023123007544716400_ref4","first-page":"779","article-title":"Case report of schwannoma of the rectum--clinical and pathological contribution","volume":"6","author":"Maciejewski","year":"2000","journal-title":"Med Sci Monit"},{"key":"2023123007544716400_ref5","doi-asserted-by":"crossref","first-page":"762","DOI":"10.1097\/00000478-199806000-00015","article-title":"Benign epithelioid schwannoma","volume":"22","author":"Kindblom","year":"1998","journal-title":"Am J Surg Pathol"},{"key":"2023123007544716400_ref6","doi-asserted-by":"crossref","first-page":"846","DOI":"10.1097\/00000478-200107000-00002","article-title":"Schwannomas in the colon and rectum","volume":"25","author":"Miettinen","year":"2001","journal-title":"Am J Surg Pathol"},{"key":"2023123007544716400_ref7","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s004280000338","article-title":"Gastrointestinal stromal tumors -
