Wang Ko-Pen M.D.; Turner, J. F. M.D.Journal of Bronchology: April 1996 Brief Report: PDF Only Free Abstract A 46-year-old male patient was treated for a chronic obstructive pulmonary disease (COPD) over 8 months because of progressive shortness of breath (SOB). When a plain chest x-ray showed atelectasis of the left lower lobe, a computed tomography (CT) scan was performed followed by a flexible bronchoscopy; both showed a tumor obstructing the left main bronchus. This lesion was successfully removed by Nd:YAG laser through a flexible bronchoscopy. A follow-up flexible bronchoscopy performed 6 months later showed a normal airway without any mucosal abnormality at the area of previous tumor. © Williams & Wilkins 1996. All Rights Reserved.
