A colonic perineurioma is a relatively recently described entity and sometimes encountered in specimens from the large intestine, especially distal colon. Without its recognition, a perineurioma can be misdiagnosed as other more common gastrointestinal spindle cell neoplasms. Here, we describe a case of colonic perineurioma with polypoid growth extruding into the intestinal lumen. Case. A woman in her seventh decade of life underwent a follow-up colonoscopy after an uneventful resection of a benign colonic polyp. A previously undetected 6-mm polyp was found in the sigmoid colon and was resected endoscopically. Microscopic examination of the lesion revealed a proliferation of bland spindle cells in the lamina propria mucosae, which were immunohistochemically positive for epithelial membrane antigen, claudin 1, and glucose transporter-1. A colonic perineurioma was diagnosed.<\/jats:p>","DOI":"10.1177\/1179555718815918","type":"journal-article","created":{"date-parts":[[2018,12,6]],"date-time":"2018-12-06T03:43:52Z","timestamp":1544067832000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["A Colonic Perineurioma"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4351-324X","authenticated-orcid":false,"given":"Tomoyuki","family":"Otani","sequence":"first","affiliation":[{"name":"Department of Diagnostic Pathology, Nara Medical University, Kashihara, Japan"},{"name":"Department of Diagnostic Pathology, Minami-Nara General Medical Center, Yoshino, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kinta","family":"Hatakeyama","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology, Nara Medical University, Kashihara, Japan"},{"name":"Department of Diagnostic Pathology, Minami-Nara General Medical Center, Yoshino, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emi","family":"Ohtani","sequence":"additional","affiliation":[{"name":"Departments of Diagnostic Pathology, Gastroenterology, Minami-Nara General Medical Center, Yoshino, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susumu","family":"Nakayama","sequence":"additional","affiliation":[{"name":"Department of General Internal Medicine, Minami-Nara General Medical Center, Yoshino, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Fujimoto","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Minami-Nara General Medical Center, Yoshino, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiho","family":"Ohbayashi","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology, Nara Medical University, Kashihara, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,12,6]]},"reference":[{"key":"bibr1-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200403000-00010"},{"key":"bibr2-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e318160df3f"},{"key":"bibr3-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000154130.87219.2c"},{"key":"bibr4-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.2006.02357.x"},{"key":"bibr5-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e3181f4a458"},{"key":"bibr6-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e318224d9df"},{"key":"bibr7-1179555718815918","doi-asserted-by":"publisher","DOI":"10.1186\/s13000-018-0694-z"}],"container-title":["Clinical Medicine Insights: Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1179555718815918","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1179555718815918","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1179555718815918","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T03:40:50Z","timestamp":1777693250000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1179555718815918"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,1]]},"references-count":7,"alternative-id":["10.1177\/1179555718815918"],"URL":"https:\/\/doi.org\/10.1177\/1179555718815918","relation":{},"ISSN":["1179-5557","1179-5557"],"issn-type":[{"value":"1179-5557","type":"print"},{"value":"1179-5557","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,1]]},"article-number":"1179555718815918"}}
