We report here a case of relapsing polychondritis (RPC), who responded to salazosulfapyridine (SASP) after 1.5 years of active disease. A 15-year-old girl having chondritis of bilateral auricles, nose and respiratory tract, ocular inflammation, cochlear and vestibular dysfunction and seronegative polyarthritis was diagnosed as RPC, and oral corticosteroid was initially effective. She was admitted to our hospital with obstructive tract chondritis and was refractory to any of the treatment such as intravenous (i.v.) pulse steroid therapy, i.v. pulse cyclophosphamide (CPA), oral intermittent methotrexate (MTX) and high dose i.v. gamma globulin. Although she was partly responsive to oral cyclosporine A (CsA), but clinical symptoms did not completely subside. SASP, initiated in combination with oral corticostreroid and CsA, however, was successful not only to show steroid sparing effect but also to induce complete remission. SASP might be useful to refractory case of RPC.
