Bronchial anthracofibrosis is one of the main manifestations of lung disease that is related to woodsmoke inhalation, and it is frequently associated with various pulmonary diseases, such as tuberculosis. The purpose of this study was to evaluate the clinical significance of bronchial anthracofibrosis in patients with endobronchial tuberculosis.

63 patients, who were diagnosed with endobronchial tuberculosis using bronchoscopy, were included in this study. The patients consisted of 12 males and 51 females, having mean age of 59.5 years. The clinical features, radiologic and bronchoscopic findings between the patients with (37) and without (26) bronchial anthracofibrosis were analyzed retrospectively.

When the patients were older, bronchial anthracofibrosis was more frequent. The endobronchial tuberculosis, which was located at the right middle lobal bronchus, was more frequent in the patients with bronchial anthracofibrosis than in the patients without bronchial anthracofibrosis. In the morphologic types of endobronchial tuberculosis, patients with bronchial anthracofibrosis had more edematous-hyperemic and ulcerative types, while patients without bronchial anthracofibrosis had more active caseating.

These findings suggest that the presence of bronchial anthracofibrosis can possibly influence the locations and morphologic types of endobronchial tuberculosis.
