In the 3100 cases of bronchoscopy performed in our hospital, 12 cases of OLC were found. In the past 26 years, only 2 cases were found in hard bronchoscopy. Now 14 cases are reported in the next. Clinical data were 13 males and 1 female. 45 cases were 45 to 50 years old, 8 cases were 51 to 60 years old, and 4 cases were 61 years old or older. There were 13 cases of smoking history.
