Bronchial tuberculosis is not extrapulmonary tuberculosis, but a subtype of pulmonary tuberculosis. Because bronchial tuberculosis, like pulmonary tuberculosis, is an infectious disease of the respiratory tract caused by infection with Mycobacterium tuberculosis, there is only a slight difference in the site of infection. Most of the lesions of pulmonary tuberculosis infection are in the lung tissue, and most of them involve the bronchi, while bronchial tuberculosis infection is mainly confined to the bronchi and does not involve the respiratory bronchioles, alveoli, and other lung tissues. Therefore, in terms of the scope of lesions, the scope of pulmonary tuberculosis includes the scope of bronchial tuberculosis. Therefore, bronchial tuberculosis belongs to the scope of pulmonary tuberculosis, not extrapulmonary tuberculosis. Extrapulmonary TB refers to TB lesions that occur far from the lungs, such as common bone TB, intestinal TB, peritoneal TB, as well as liver TB, brain TB, etc.
