Advancements in immunohistochemical techniques have allowed for the differentiation between LMSs and gastrointestinal stromal tumors. LMSs remain difficult to detect via endoscopy and require a more intricate diagnostic approach. The staging and sizing of these tumors are important prognostic indicators. We report a case of a 67-year-old male who presented with bulging lower extremity veins, abdominal bloating, and weight loss. A CT of the abdomen and pelvis revealed a pelvic mass arising from the small bowel and a metastatic hepatic lesion, which was found to be compressing the inferior vena cava. A biopsy of the hepatic lesion confirmed the diagnosis of metastatic LMS. <\/jats:p>","DOI":"10.1159\/000520802","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T14:06:35Z","timestamp":1639058795000},"page":"1-4","source":"Crossref","is-referenced-by-count":4,"title":["Lower Extremity Varicose Veins: An Unusual Presentation of Small Bowel Leiomyosarcoma"],"prefix":"10.1159","volume":"9","author":[{"given":"Karim","family":"Abou El Joud","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Misha","family":"Abbasi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2021,11,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3322\/CA.2007.0010"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.anndiagpath.2012.07.005"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197809)42:3%3c1375::aid-cncr2820420348%3e3.0.co;2-4"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.suc.2010.10.011"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1038\/nrclinonc.2013.132"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v19.i47.9133"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19810515)47:10%3c2391::aid-cncr2820471012%3e3.0.co;2-b"}],"container-title":["Gastrointestinal Tumors"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/520802","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/520802","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:32:59Z","timestamp":1745422379000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000520802"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,11,18]]},"references-count":7,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,3,28]]},"published-print":{"date-parts":[[2022,3,15]]}},"URL":"https:\/\/doi.org\/10.1159\/000520802","archive":["Portico"],"relation":{},"ISSN":["2296-3774","2296-3766"],"issn-type":[{"type":"print","value":"2296-3774"},{"type":"electronic","value":"2296-3766"}],"subject":[],"published":{"date-parts":[[2021,11,18]]}}}
