Pulmonary mucormycosis is an opportunistic infection in patients with severe underlying illness such as immunocompromised diseases or uncontrolled diabetes mellitus. While patients with leukemia and lymphoma usually resent with diffuse parenchymal disease, diabetic patients usually have a localized endobronchial disease involving central airways. We report upon a case of pulmonary mucormycosis in diabetes mellitus patient presenting as an endobronchial mass, which was cured with antifungal therapy, rigid bronchoscopic mass removal and right pneumonectomy.
