Abstract

A case of broncholithiasis excised by bronchofiberscopy using biopsy forceps was reported. A 52 year old female was admitted to the course of our hospital for detached examination of hemoptysis. She had previously suffered from pulmonary tuberculosis. Bronchofiberscopic examination revealed complete obstruction by yellowish-white materials in the orifice of left B^4. We attemped bronchoscopic excision of the materials and succeeded in removal using by conventional biopsy forceps without bleeding. After the excision bronchi peripheral to B^4 were found to be intact without perforation or thickening of the bronchial wall. Histological examination demonstrated a broncholithiasis with stratified the calcification and suppuration. Chest roentogenogram showed scattered calcification in both lung fields without hilar lymph node calcification, Moreover CT scanning revealed no hilar lymph node calcification, and there was no perforation of bronchial wall of left B^4. Therefore, its origin was considered to be retained bronchial mucus with infection.
