Endobronchial Neurogenic Tumors Treated by Transbronchial Electrical Snaring and Nd-YAG Laser Abrasion: Report of Three Cases

Abstract

Neurogenic benign tumors arising from the trachea and bronchus are relatively rare. We experienced three cases of neurofibroma of the bronchus which were successfully treated by transbronchial electrical snaring and Nd-YAG laser abrasion. The first was a 67-year-old man with right lung cancer, who was pointed out to have a neurofibroma in the left main bronchus. The second was a 34-year-old man with an obstruction in the right main bronchus due to neurofibroma. The third was a 66-year-old woman with a complete obstruction in the left main bronchus due to schwannoma. All patients were successfully treated to remove the tumors and obtain a patency of the bronchus by transbronchial electrical snaring and Nd-YAG laser abrasion. We also review 23 reported cases of endobronchial neurogenic tumors and discuss the efficacy of endoscopic treatments for endobronchial neurogenic tumors.
