Objective: Primary benign tumors of the trachea and main bronchi are uncommon. Interventional bronchoscopy allows the diagnosis and the treatment of some of these lesions. Methods: We reviewed four cases endoscopically treated at our institution. Results: Two patients had hamartoma, and two patients had endobronchial lipoma. In all of the cases, the interventional technique for the resection was the use of a polypectomy snare and electrocautery. The only complication reported was one episode of bronchospasm. Conclusions: Minimally invasive bronchoscopic resection is a safe, effective method for treating selected benign tumors of the main airway and has a low complication rate.
