[A case of infected bulla caused by Mycobacterium gordonae].

A 65-year-old man was admitted to Tokyo Metropolitan Geriatric Medical Center because of dyspnea on effort, loss of appetite and general fatigue. Chest radiography on admission showed niveau formation in, and infiltration around, the bulla. Percutaneous drainage of the intrabullous fluid was performed and Mycobacterium gordonae was repeatedly cultured from it. The patient was treated with RFP, INH and CAM and the intrabullous fluid and infiltration around the bulla was markedly improved. Seven cases of pulmonary infection by M. gordonae have been reported in Japan, but this is the first case of bulla infected by this organism.
