These tumors tend to recur despite surgical resection, due to extensive tumor infiltration of the sub-mucosa. The appearance in this case is strictly endotracheal. Resection has been complicated by abundant bleeding due to the presence of a sizeable feeding vessel. Despite satisfactory results, the tumor recurred two years later.
Airway wall infiltration is extensive providing the laser with a large margin of error. In this case, the endoscopist can literally create a new airway. Relapse, however, is almost certain. These tumors are chemoresistant. Radiation therapy is usually not helpful either, making stent placement necessary in order to secure an airway lumen.
This case is similar. Endoscopic treatment is often complicated by bleeding, although the latter is often well-controlled with the laser.
