[Fulminant tracheobronchitis caused by methicillin-resistant Staphylococcus aureus (MRSA)].

A 56-year-old man was admitted to our hospital because of hemoptysis, and dyspnea. Breathing sounds decreased and rhonchi was audible in the right lung. Chest X-ray and Chest CT showed infiltrative shadows in the bilateral lower lobes. He was intubated and bronchofiberscopy revealed mucosal necrosis and hemorrhage of the lower trachea and the bilateral bronchi. MRSA was isolated from sputum and bronchial lavage fluids. He was diagnosed as NTB caused by MRSA. On the 7th day in hospital, he suffocated by the necrotic tissue and autopsy was performed. NTB is a very uncommon disease in adults, especially ones who are not under mechanical ventilation.
