SS accounts for 5% to 10% of soft-tissue sarcomas. These tumors occur mostly in the joints, especially near the knee, but they also occur in other locations. Primary intravascular SS (IVSS) are extremely rare; only 6 well-documented cases have been reported in the English literature. We describe a new case of primary IVSS of the superior vena cava (SVC) in a 16-year-old boy. A transthoracic echocardiogram confirmed a large (4.8 \u25ca 4.6 cm) circumscribed mass filling the right atrium, as well as a moderate pericardial effusion. The mass extended from the SVC to the tricuspid valve but did not prevent valve coaptation. Surgery via a transatrial approach revealed a huge mass (8 to 12 cm) attached to the SVC via a 5-mm pedicle. The tumor was excised, and the patient experienced an uneventful postoperative course. Fluorescence in situ hybridization analysis revealed the presence of the SS-specific translocation.<\/jats:p>","DOI":"10.1532\/hsf98.20111159","type":"journal-article","created":{"date-parts":[[2012,10,23]],"date-time":"2012-10-23T21:09:42Z","timestamp":1351026582000},"page":"297","source":"Crossref","is-referenced-by-count":4,"title":["Primary Intravascular Synovial Sarcoma: Case Report"],"prefix":"10.31083","volume":"15","author":[{"given":"Osman Nuri","family":"Tuncer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ozan","family":"Erbasan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u0130lhan","family":"Golbasi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2012,10,23]]},"reference":[{"key":"1","doi-asserted-by":"crossref","first-page":"224","DOI":"10.1016\/j.ejvs.2008.01.028","article-title":"Primary intravascular synovial sarcoma of the femoral vein in a male patient, case report","volume":"36","author":"M.
