Two cases of large tracheobronchial schwannomas completely resected by rigid bronchoscopy with multiple instruments

Primary tracheobronchial schwannomas are extremely rare. Surgical treatment has been the first choice for these benign tumours due to the substantial residual rates and recurrences after bronchoscopic resection. In addition, there has been limited information on bronchoscopic removal of endobronchial schwannomas. We describe two cases of large tracheal and bronchial schwannomas that were completely and successfully resected by snare electrocautery, insulation-tipped knife, and argon plasma coagulation under rigid bronchoscopy. These cases highlight that rigid bronchoscopic treatment with these multiple instruments can be a good treatment option for endotracheal or endobronchial schwannomas.
