We experienced a patient with Legionella Pneumonia immediately after discharge from COVID-19. It is very important to accurately detect pathogens of infectious diseases particularly in the time of COVID-19 pandemic.

We experienced a case with accidental aspiration of a metallic round foreign body. As there is no established techniquefor retrieving a metallic round ball from an airway, we propose that endoscopic net forceps with the support of a laryngeal mask airway is the best choice for such occasions.
