Tenosynovial Giant Cell Tumor of Knee with Limited Range of Motion: Case Report

Abstract

A case of tenosynovial giant cell tumor (TGCT) in the left intercondylar notch was reported. This tumor has been rarely reported until now. A-41-year-old man with left gonalgia showed limited range of motion and hemarthrosis. Although there are slight differences histologically between TGCT and localized pigmented villonodular synovitis (PVS), multinucleated giant cells and no foamy cells were present in this case, which is characteristic of TGCT. Careful follow-up is needed because of possible local recurence or invasion.
