They are comprised either an adenocarcinoma, neuroendocrine tumor, gastrointestinal stromal tumor (GIST), lymphoma, and\/or sarcoma. &lt;b&gt;&lt;i&gt;Case Presentation:&lt;\/i&gt;&lt;\/b&gt; Here we exhibit the case of a 23-year-old who presented with progressive nausea, weight loss, abdominal pain, and iron deficiency anemia and was diagnosed with leiomyosarcoma of the jejunum. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; We distinguish a GIST from leiomyosarcoma based on radiographic, histologic, and epidemiologic evidence and review the significance of prompt, accurate diagnosis as related to treatment. <\/jats:p>","DOI":"10.1159\/000538430","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T21:00:34Z","timestamp":1713387634000},"page":"38-43","source":"Crossref","is-referenced-by-count":0,"title":["Jejunal Leiomyosarcoma in a Young Adult: Distinguishing from Gastrointestinal Stromal Tumor through Radiographic, Histologic, and Epidemiologic Analysis \u2013 A Case Report"],"prefix":"10.1159","volume":"10","author":[{"given":"Blake H.","family":"Bentley","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abigail L.","family":"Ellington","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alyssa A.","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiyan","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William C.","family":"Lippert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2024,4,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0b013e31818e4641"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.29328\/journal.acgh.1001037"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2007.05.022"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199501053320103"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1053\/hupa.2002.30214"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1080\/1357714021000065404"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.surge.2014.02.003"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s002689910067"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.anndiagpath.2012.07.005"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.4251\/wjgo.v2.i5.222"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1002\/jso.20105"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2006.11.012"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.5114\/pjp.2022.124478"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e318186b158"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.14.068"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200407000-00007"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-6-131"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(11)70299-6"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2007.13.4452"}],"container-title":["Gastrointestinal Tumors"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/gat\/article-pdf\/10\/1\/38\/4229285\/000538430.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/gat\/article-pdf\/10\/1\/38\/4229285\/000538430.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:12:52Z","timestamp":1745421172000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000538430"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023]]},"references-count":19,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2024,5,16]]}},"URL":"https:\/\/doi.org\/10.1159\/000538430","archive":["Portico"],"relation":{},"ISSN":["2296-3774","2296-3766"],"issn-type":[{"type":"print","value":"2296-3774"},{"type":"electronic","value":"2296-3766"}],"subject":[],"published":{"date-parts":[[2023]]}}}
