Relapsing polychondritis: new pulmonary manifestations.

Relapsing polychondritis is purported to be an autoimmune disease characterized by inflammation of cartilaginous structures including the nose, ears, glottis, trachea, and mainstem bronchi. Arthropathy, aortopathy, scleritis, conjunctivitis, iritis, vertigo, otitis media, glomerulonephritis, and skin lesions are common manifestations. We have recently cared for an elderly nonsmoker with a history of abdominal aortic aneurysm repair and recurrent bouts of painful ear swelling who presented with a pulmonary infiltrate and pulmonary function studies suggestive of small airways disease. Subsequent transbronchial biopsy revealed no pathogens but was associated with excessive bleeding, perhaps suggestive of a vasculitic process in the lung. The pulmonary infiltrate cleared over a 2-month interval with the use of corticosteroids. Unusual in this otherwise classical case of relapsing polychondritis was that the pulmonary infiltrate and small airways disease were the prominent pulmonary manifestations and no tracheobronchial abnormalities were visualized.
