Two Cases of Diagnosis and Removal of Endobronchial Hamartoma by Cryotherapy via Flexible Bronchoscopy
A 53-year-old man was referred to our hospital for bronchoscopic evaluation for abnormal density in front of superior segmental bronchus of left lower lung (LB6) on chest CT on personal health examination (). The bronchoscopic examination with autofluorescence bronchoscopy showed LB6 was obstructed by pedunculated mass. The cryotherapy was performed for endobronchial biopsy and tumor cryodebridement with same above described procedures. The mass was successfully removed with small amount of bleeding (). The bleeding was controlled by iced saline. The biopsy result of removed mass was hamartoma (). Chest X-ray at 1 month after resection of endobronchial hamartoma showed normal chest X-ray finding (). And bronchoscopic examination after 1 month after removal showed good patency without any obstruction of LB6 ().
