Furthermore, a colonic pedunculated leiomyoma is very rare. Complete endoscopic removal of a colonic leiomyoma can be problematic because of its submucosal origin. &lt;b&gt;&lt;i&gt;Case Report:&lt;\/i&gt;&lt;\/b&gt; We report a colonic pedunculated leiomyoma that was removed by endoscopic polypectomy without complications. A 74-year-old man was referred to our hospital because of constipation. Colonoscopy demonstrated a 1-cm pedunculated polyp that was connected to a minute stalk within the sigmoid colon. It was removed by snare polypectomy. Histopathological examination demonstrated normal mucosa overlying a well-circumscribed proliferation of eosinophilic spindle cells arising in association with the muscularis mucosae. Immunohistological findings were positive for desmin and smooth muscle actin. The polyp was diagnosed as a leiomyoma. More than 9 months later, the patient remains well, with no further symptoms. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; For small, pedunculated leiomyomas, endoscopic snare polypectomy is thought to be a useful approach for both treatment and diagnosis.<\/jats:p>","DOI":"10.1159\/000368791","type":"journal-article","created":{"date-parts":[[2014,12,8]],"date-time":"2014-12-08T14:24:05Z","timestamp":1418048645000},"page":"427-429","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic Removal of Pedunculated Leiomyoma of the Sigmoid Colon"],"prefix":"10.1159","volume":"30","author":[{"given":"Harunobu","family":"Sato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihisa","family":"Mizuno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Tsukamoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoaki","family":"Ichikawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihito","family":"Kotani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsuyuki","family":"Honda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Kuroda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2014,12,3]]},"container-title":["Visceral Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/368791","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/368791","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/368791","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:54:41Z","timestamp":1745430881000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000368791"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2014,12,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000368791","archive":["Portico"],"relation":{},"ISSN":["2297-4725","2297-475X"],"issn-type":[{"value":"2297-4725","type":"print"},{"value":"2297-475X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
