Ulcerative and Plaque-Like Tracheobronchitis Due to Infection with Aspergillus in Patients with AIDS

Abstract

Tracheobronchitis is an uncommon manifestation of infection due to Aspergillus species, occurring in Aspergillus species demonstrated histologically. Three patients had received corticosteroids or were neutropenic at presentation. At bronchoscopy, three patients had some degree of diffuse tracheobronchitis, multiple ulcerative or “plaque-like” inflammatory lesions, and occasionally nodules involving the mainstem and segmental bronchi. The remaining patient had a single deep ulceration of the proximal trachea. Aspergillus was isolated from biopsy specimens from all four patients. There were varied degrees of invasion of the mucosa, submucosa, and cartilage on histological examination in three patients, one of whom had evidence of disseminated aspergillosis. Two patients subsequently developed pulmonary parenchymal disease due to Aspergillus. A review of aspergillus tracheobronchitis, including a discussion of airway disease in patients infected with human immunodeficiency virus, is presented.
