A Tenosynovial Giant Cell Tumor Arising from Femoral Attachment of the Anterior Cruciate Ligament

Abstract

The localized type of tenosynovial giant cell tumor usually occurs on the palmar side of fingers and toes. Tenosynovial giant cell tumors of the tendon sheath are rarely intra-articular. We report a giant cell tumor of the tendon sheath arising from femoral attachment of the anterior cruciate ligament and its treatment with arthroscopy in a 28-year-old man.

A rare case of giant cell tumour arising from anterior cruciate ligament: Its diagnosis and management

“…The knee was found to be stable after the excision. 13 In our case to begin with, the diagnostic arthroscopy was performed through anteromedial and anterolateral portals. A posterolateral portal was used to gain better access for complete excision of the tumour.…”

“…13,14 Lee at al. 13 reported a case of 29-year-old man affected by an intra-articular localized tenosynovial giant cell tumour of the tendon sheath arising from the ACL. On MRI the mass was situated behind the ACL and was attached near to its femoral attachment.…”

Higher incidence of diffuse Pigmented Villonodular Synovitis in patients with ruptured cruciate ligament: A case report

“…While due to the high recurrence of diffuse PVNS, finding more effective therapies for PVNS remains a theme of dispute. In a retrospective review of the patients who accepted surgical treatment between 1990 and 2022 [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , the results exhibit that higher recurrence rate of arthroscopic synovectomy compared with open synovectomy, However, the arthroscopic therapy is a minimally aggressive surgical operation that could narrow the scope of operation, lessen tissue trauma, and promote early functional exercise, allowing the earlier return to the daily life [24] . The combined anterior arthroscopic and posterior open synovectomy in the knee could be a good option because some researches have shown that the recurrence rate of it is lower than arthroscopic synovectomy and open synovectomy.…”

Tumor de Células Gigantes Tenossinovial em joelho relato de caso

“…Os TTCG são raros, correspondendo a aproximadamente 1,5% do total de tumores de tecidos moles 1 . São mais frequentemente observados em pacientes com idade entre 30 Brazilian Journal of Development, Curitiba, v.9, n.8, p. 25252-25258, aug., 2023 e 50 anos, com maior prevalência no sexo feminino (2:1) 3,4,5 . Podem acometer qualquer articulação sinovial, incluindo o quadril, tornozelo, ombro e cotovelo e há também registros de forma poli articular em crianças 8,9 .…”
