Since nodular fasciitis is not widely recognized to arise within the joints, it may therefore cause diagnostic confusion in this uncommon setting. We report an unusual tumor of an 11-year-old patient who presented with a 6-month history of right elbow swelling and pain. Histology revealed that the tumor was composed solely of proliferating bland spindle cells with osteoclast-like giant cells and scattered foam cells. There was only a focal area of immature granulation-like myxoid change, which suggested nodular fasciitis. Molecular analysis using next-generation sequencing revealed gene rearrangement involving\n                    <jats:italic toggle=\"yes\">USP6<\/jats:italic>\n                    and\n                    <jats:italic toggle=\"yes\">MYH9<\/jats:italic>\n                    , supporting the diagnosis of nodular fasciitis within the elbow joint.
