Lacking the possibility of distant metastases, local surgical resection with a clear margin can achieve the purpose of treatment. Endoscopic submucosal dissection has been widely used in the treatment of early upper gastrointestinal cancer and superficial hypopharyngeal cancer. Here, we present a case of a giant tumor originated from the hypopharynx that received primary resection by endoscopic submucosal dissection using a flexible upper gastroscope.<\/jats:p>","DOI":"10.1177\/01455613221096624","type":"journal-article","created":{"date-parts":[[2022,5,18]],"date-time":"2022-05-18T18:12:10Z","timestamp":1652897530000},"page":"173-175","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Endoscopic Submucosal Dissection for a Giant Well-Differentiated Liposarcoma Originated from Hypopharynx"],"prefix":"10.1177","volume":"104","author":[{"given":"Xu","family":"Zhou","sequence":"first","affiliation":[{"name":"E.N.T. department, Zhongshan Hospital, Fudan University, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao-Yue","family":"Xu","sequence":"additional","affiliation":[{"name":"Endoscopy Center and Endoscopy Research Institute, Zhongshan Hospital, Shanghai Collaborative Innovation Center of Endoscopy, Fudan University, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5434-0540","authenticated-orcid":false,"given":"Ping-Hong","family":"Zhou","sequence":"additional","affiliation":[{"name":"Endoscopy Center and Endoscopy Research Institute, Zhongshan Hospital, Shanghai Collaborative Innovation Center of Endoscopy, Fudan University, Shanghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,5,11]]},"reference":[{"key":"bibr1-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1308\/rcsann.2020.0179"},{"key":"bibr2-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19950915)76:6<1051::AID-CNCR2820760620>3.0.CO;2-4"},{"key":"bibr3-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1007\/s12029-016-9808-6"},{"key":"bibr4-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-020-05789-4"},{"key":"bibr5-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1016\/j.anorl.2017.07.001"},{"issue":"1","key":"bibr6-01455613221096624","first-page":"e13","volume":"32","author":"Muramoto T","year":"2020","journal-title":"Dig Endosc"},{"key":"bibr7-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1309720"},{"key":"bibr8-01455613221096624","doi-asserted-by":"publisher","DOI":"10.1111\/den.13883"}],"container-title":["Ear, Nose &amp; Throat Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/01455613221096624","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/01455613221096624","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/01455613221096624","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T18:36:33Z","timestamp":1777401393000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/01455613221096624"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,11]]},"references-count":8,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025,3]]}},"alternative-id":["10.1177\/01455613221096624"],"URL":"https:\/\/doi.org\/10.1177\/01455613221096624","relation":{},"ISSN":["0145-5613","1942-7522"],"issn-type":[{"value":"0145-5613","type":"print"},{"value":"1942-7522","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,5,11]]}}}
