Acute tracheobronchitis is a rare clinical manifestation of respiratory tract invasive aspergillosis, sporadically reported in patients with hematological malignancies against the background of conventional chemotherapy. The authors report on a case of pseudomembranous necrotizing form of histologically proven tracheobronchitis, caused by Aspergillus spp in the time of induction chemotherapy in a patient with acute myeloid leukemia. The clinical evolution is gradual: from mild non-specific manifestations of acute tracheobronchitis against the background of a prolonged fever unaffected by antibiotic therapy to the onset of severe acute respiratory insufficiency and unilateral bronchial obstruction syndrome. Multiple spontaneous expectoration of a part of the bronchial wall was observed in which Aspergillus spp hyphae were histologically proven. Tracheobronchoscopy verified nearly complete obturation of the left main bronchus with thick mucous plugs. Lethal outcome from the infection occurred at the stage of hematological remission because of a massive hemoptysis. The diagnostic methods, therapeutic possibilities and differential diagnosis of this rare infectious complication in immunocompromised patients are discussed.

A 34-year-old man presented with scanty hemoptysis, orange-colored expectoration, and mild dyspnea. He was in an enclosed building taking part in a military training exercise inhaling an orange-colored smoke from a smoke grenade ignition. His symptoms developed immediately after the initial exposure but he sought medical assistance 20 hours later because of their persistence. Fiberoptic bronchoscopy was performed revealing diffuse inflammatory tracheobronchial tree with streaky orange-pigmented secretions in the trachea and both main-stem bronchi. Acute tracheobronchitis was diagnosed and the patient was treated with nebulized bronchodilators and intravenous corticosteroids showing complete recovery. To our knowledge, this is the first well-documented report of inhalation injury induced by a smoke bomb explosion including potassium chlorate oxidizer and Sudan I and presenting with orange-pigmented sputum production. Smoke inhalation injury is associated with significant morbidity and mortality. The heterogeneity of the smoke and the large variety of the resulting symptoms may be the reason why a definition, specific diagnostic criteria, and therapeutic guidelines are still lacking.
