Pyopneumothorax with bronchopleural fistula due to pulmonary infection caused by Porphyromonas gingivalis in a patient with periodontitis

Pyopneumothorax with bronchopleural fistula is a rare complication of lung infection. We herein report a case of pyopneumothorax with bronchopleural fistula caused byPorphyromonas gingivalis infection, a common pathogenic pathogen of periodontitis, in a 49-year-old man with periodontitis. The patient was admitted with respiratory failure. Pleural puncture yielded a lot of gas continually and foul-smelling light brown pus, which was found to be caused due to infection withP.  gingivalis by the next generation sequencing (NGS) and anaerobic culture.
