Localized pigmented villonodular synovitis (PVNS), a subtype of TSGCT, commonly affects the hands and feet and has also been reported in the literature in the knee joint. There is sparse literature on localized PVNS arising specifically from meniscal tissue. We present a case report of a 17-year- old male with symptoms and MRI findings consistent with a lateral meniscus tear. Intraoperatively, the patient was found to have a mass originating from the torn meniscal tissue, which was confirmed by pathology to be a TSGCT. We performed a literature review of intra-articular localized PVNS within the knee presenting as a meniscal tear.<\/jats:p>","DOI":"10.1055\/s-0041-1735463","type":"journal-article","created":{"date-parts":[[2021,9,10]],"date-time":"2021-09-10T23:06:33Z","timestamp":1631315193000},"page":"431-434","source":"Crossref","is-referenced-by-count":0,"title":["Localized Pigmented Villonodular Synovitis Originating from the Lateral Meniscus in a 17-year-old: Case Report and Literature Review of Meniscal-Associated Localized PVNS"],"prefix":"10.1055","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5058-4740","authenticated-orcid":false,"given":"Rachel C.","family":"Talley-Bruns","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Westchester Medical Center\/New York Medical College, Valhalla, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9633-0121","authenticated-orcid":false,"given":"Ruby G.","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Westchester Medical Center\/New York Medical College, Valhalla, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2989-0890","authenticated-orcid":false,"given":"Jeremy E.","family":"Mangion","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Westchester Medical Center\/New York Medical College, Valhalla, New York"},{"name":"Department of Orthopedic Surgery MidHudson Regional Hospital, Poughkeepsie, New York"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,9,10]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"bcr2017219549","DOI":"10.1136\/bcr-2017-219549","article-title":"A rare case of localised pigmented villonodular synovitis in the knee of a 24-year-old female soccer player: diagnosis, management and summary of tenosynovial giant cell tumours","volume":"2017","author":"C Falster","year":"2017","journal-title":"BMJ Case Rep"},{"issue":"07","key":"ref2","doi-asserted-by":"crossref","first-page":"e3","DOI":"10.2106\/JBJS.RVW.15.00086","article-title":"Pigmented villonodular synovitis: a comprehensive review and proposed treatment algorithm","volume":"4","author":"S R Stephan","year":"2016","journal-title":"JBJS Rev"},{"issue":"02","key":"ref3","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1007\/s11832-009-0236-z","article-title":"Pigmented villonodular synovitis of the knee in skeletally immature patients","volume":"4","author":"E Baroni","year":"2010","journal-title":"J Child Orthop"},{"key":"ref4","first-page":"840243","article-title":"Localized giant cell tenosynovial tumor seen in the knee joint","volume":"2014","author":"O Beytem\u00fcr","year":"2014","journal-title":"Case Rep Orthop"},{"issue":"03","key":"ref5","first-page":"173","article-title":"Localized pigmented villonodular synovitis: three cases of intra-articular knee involvement","volume":"16","author":"E Harris","year":"2003","journal-title":"J Knee Surg"},{"issue":"02","key":"ref6","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1016\/j.otsr.2013.09.017","article-title":"Localized form of pigmented villonodular synovitis of the knee: the meniscal mime","volume":"100","author":"N Bouguennec","year":"2014","journal-title":"Orthop Traumatol Surg Res"},{"issue":"03","key":"ref7","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1097\/00005792-198005000-00004","article-title":"Pigmented villonodular synovitis and tenosynovitis: a clinical epidemiologic study of 166 cases and literature review","volume":"59","author":"B W Myers","year":"1980","journal-title":"Medicine (Baltimore)"},{"issue":"01","key":"ref8","doi-asserted-by":"crossref","first-page":"76","DOI":"10.2106\/00004623-198466010-00012","article-title":"Pigmented villonodular synovitis (giant-cell tumor of the tendon sheath and synovial membrane).
