Abstract
A 52-year-old female was admitted with cough and sputum. Chest X-ray and chest CT showed atelectasis of the left upper lobe. Bronchofiberscopic examination revealed a tumor obstructing the left upper bronchus. Diagnosis by bronchoscopic biopsy and removal of the tumor was attempted many times, but failed. Left upper sleeve lobectomy was performed. Three foreign bodies (pieces of wood) in the resected specimen were demonstrated. It is necesary to suspect foreign bodies in such cases.
