Endoscopic removal is acceptable for the treatment of endotracheal/endobronchial mass, because it is less invasive in high-risk patients and a conservative procedure for benign tumors. Two benign tumors in the lumen of the trachea (pure lipoma) and in the intermediate bronchus (hamartoma) were completely eradicated by our procedures, which involved diathermic snaring and residual mass removal with biopsy forceps under the guidance of fiberoptic bronchoscopy. No tumor recurrence was evident after extended follow-up (6 years for endotracheal lipoma and 2.5 years for endobroncheal hamartoma). Our method is safe and less invasive for the patient and provides the surgeon with better view during procedure.
