case_images: (A) Initial bronchoscopy showed near complete stenosis of the left main bronchus covered by scale-like neoplasms. (B) Follow-up bronchoscopy two months later showed approximately 50% stenosis of the left main bronchus and luminal patency of the right main bronchus. The arrows indicate the location of the lesion.

case_images: Postoperative pathology revealed a leiomyoma at the opening of the left main bronchus ( Figure 2D ).
case_images: (A) Bronchoscopy showed a granular neoplasm in the right lower lateral wall of the main trachea, obstructing about 40% of the airway. (B) Bronchoscopy after eight months showed 15% airway stenosis at the original lesion site. The arrows indicate the location of the lesion.

case_images: The tumor was irregular in shape, firm, tended to bleed on palpation, and obstructed approximately 40% of the airway ( Figure 3A ). Eight months later, a follow-up bronchoscopy showed approximately 15% stenosis at the original lesion site ( Figure 3B ), which was reduced to approximately 10% after additional tumor resection.

case_images: Postoperative pathology revealed a leiomyoma at the opening of the left main bronchus ( Figure 2D ).
case_images: (A) Bronchoscopy showed a new neoplasm on the left upper wall of the opening of the right main bronchus, protruding into the airway. (B) Follow-up bronchoscopy six months later showed almost complete resolution of the neoplasm. The arrows indicate the location of the lesion.

case_images: Under endobronchial ultrasound, the neoplasm showed rich blood flow ( Figure 4A ). A follow-up bronchoscopy six months later showed mild mucosal thickening and elevation at the original lesion site in the right main bronchus, which was treated with multiple carbon dioxide cryoablations ( Figure 4B ).

case_images: (A) Bronchoscopy showed a spherical tumor at the distal end of the left main bronchus, almost completely obstructing the airway.(B) Follow-up bronchoscopy 12 months later showed a patent distal end of the left main bronchus. The arrows indicate the location of the lesion.

case_images: The tumor, with a surface showing tortuous blood vessels, was of intraluminal + wall-invading type, completely obstructing the left main bronchus ( Figure 5A ). The dorsal segment opening was not visible, but the basal segment opening was patent ( Figure 5B ).
