title: Osteolysis syndrome mimicking juvenile idiopathic arthritis.
abstract: Osteolysis syndromes include a group of heterogeneous disorders that can be mistakenly diagnosed as juvenile idiopathic arthritis (JIA) in early course of the disease. We report a case of 16-year-old girl who presented with severe joint deformities, subcutaneous nodules and linear skin indurations. She had been diagnosed as having JIA before and given immunosuppressive therapy. X-ray of the joints showed severe osteopenia and osteolysis of interphalangeal joints of the hands and feet. The patient was diagnosed as having Torg/nodulosis, arthropathy, osteolysis syndrome (NAO). Here, we briefly discuss osteolysis syndromes and the differential diagnosis between osteolysis syndromes and JIA.
