| Abstract | | Intraarticular nodular fasciitis is a rare lesion that has only recently been recognised. We present a case of intraarticular nodular fasciitis of the hip joint in a 25-year-old woman, who presented with a 9-month-history of right groin pain and a decreased range of right hip motion. A polypoid mass, composed of five nodules attached to the synovial membrane of the distal peripheral compartment of the hip was removed arthroscopically, together with two detached nodules. Histopathological examination revealed a myofibroblastic proliferation typical of nodular fasciitis. Complete resolution of symptoms and restoration of function was achieved, without recurrence 2 years after removal of the lesion. To the best of our knowledge, this is the first case of intraarticular nodular fasciitis of the hip, presenting a new indication for arthroscopic treatment.
