A 52-year-old woman was diagnosed with bilateral necrotizing scleritis (NS) and peripheral ulcerative keratitis secondary to the antineutrophil cytoplasmic antibody (ANCA)-negative granulomatosis with polyangiitis (GPA) as evidenced by increased erythrocyte sedimentation rate, bilateral multiple cavitation lung nodules, and persistent microscopic hematuria. Infective workup and autoimmune tests were negative including the ANCA test. She received multiple courses of high dose intravenous methylprednisolone, intravenous cyclophosphamide, and oral methotrexate. Multiple tectonic patching operations were performed. Despite all the treatment, the disease continued to progress. Eventually, few doses of rituximab were given and the disease was stable for at least a year without any reactivation.
