ABSTRACT

A 27-year-old woman was hospitalized because of pneumonia. Antibiotic therapy was initiated but was ineffective. We performed bronchoscopy for diagnosis, which showed mucosal swelling and white plaques along the membranous portion of the trachea and main bronchus. Since the Mycoplasma pneumoniae antibody level was elevated, we made a definite diagnosis of M. pneumoniae infection, which was the cause of the plaques. A bronchoscopy performed before discharge revealed the disappearance of the mucosal swelling and white plaques. Although the frequency is unknown, M. pneumoniae infection can cause white plaques on the tracheal wall.
