title: Acute laryngeal dyspnea as first presentation of granulomatosis with polyangiitis.
abstract: Granulomatosis with polyangiitis (GPA) is a multi-organ disease which mostly affects lungs, kidney, and head and neck region. We report a rare case of acute laryngeal dyspnea and rapidly progressive pulmonary changes as first manifestations of disease. A 53 year-old woman presented with symptoms of two-week dyspnea, which aggravated rapidly in the preceding hours. Laryngological examination revealed subglottic infiltrations and vocal fold oedema which required urgent tracheotomy. During few days she developed gingival ulcerations and pulmonary infiltration with negative serum c-ANCA titers. The histopathological examination of subglottic and gingival biopsies and the clinical picture established the diagnosis of GPA. She was treated with prednisone and cyclophosphamide with recovery; however, during over 3 years of follow-up, pulmonary symptoms relapsed and subglottic stenosis persisted. The difficulties in diagnosis and treatment in this unusual presentation of GPA are outlined with conclusion that in patients with subglottic infiltration, which develops rapidly, even when this is a sole presentation of the disease, and when c-ANCA are negative, GPA should always be considered.
