A 78-year-old diabetic man presented with consolidation in the middle and lower lobe of the right lung. An endobronchial mucoid mass was found to be obstructing the right middle lobe and right lower lobe bronchi. The patient was treated with intravenous amphotericin B followed by a right pneumonectomy. Histopathology of the resected specimen demonstrated broad nonseptate hyphae branching at right angles, characteristic of mucormycosis.
