Furthermore, leiomyosarcoma accounts for 6% of all soft tissue sarcomas, and leiomyosarcoma of azygos vein origin is extremely rare. In this report, we describe a case of leiomyosarcoma derived from an azygos vein that was completely resected. A 78\u2010year\u2010old male patient was incidentally found to have a mediastinal mass during a computed tomography (CT) scan performed for the evaluation of prostate cancer. Bronchoscopic needle biopsy revealed the mass to be a leiomyosarcoma. Preoperative contrast\u2010enhanced CT demonstrated a filling defect in the azygos vein, suggesting the tumor's origin from this structure. Video\u2010assisted thoracoscopic surgery (VATS) was performed to resect the mediastinal tumor. The tumor was found to have minimal adhesions to surrounding tissues and no evidence of local invasion, although findings suggested it originated from the azygos vein. Consequently, en bloc resection of the azygos vein was performed. Postoperative histopathological examination confirmed the diagnosis of leiomyosarcoma originating from the azygos vein, and complete resection was performed.<\/jats:p>","DOI":"10.1111\/1759-7714.15467","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T16:03:40Z","timestamp":1728403420000},"page":"2395-2398","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A case of leiomyosarcoma originating from the azygos vein"],"prefix":"10.1111","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9045-4416","authenticated-orcid":false,"given":"Masatoshi","family":"Shimura","sequence":"first","affiliation":[{"name":"Division of General Thoracic Surgery, Department of Surgery Shinshu University School of Medicine  Matsumoto Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobutaka","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of General Thoracic Surgery Red Cross Hospital  Nagano Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahisa","family":"Miyazawa","sequence":"additional","affiliation":[{"name":"Department of General Thoracic Surgery Red Cross Hospital  Nagano Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,10,8]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(96)00152-X"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(95)00528-S"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(98)00718-8"},{"key":"e_1_2_9_5_1","first-page":"300","article-title":"Leiomyosarcoma of the azygos vein.
