Nosocomial pulmonary mucormycosis with fatal massive hemoptysis

We postulate that the previously healthy woman reported here developed abnormal host defense mechanisms because of acute renal failure, metabolic acidosis, hyperglycemia, and glucocorticosteroid administration. Pneumonia unresponsive to antibiotics terminated in massive fatal hemoptysis that was due to mucormycosis with rupture of the pulmonary artery into the tracheobronchial tree.
