Recognition of tuberculous disease of the trachea and the major bronchi is a recent achievement in clinical diagnosis. Although it is easy to understand why older clinicians, unaided by the roentgen film and the bronchoscope, did not suspect the existence of bronchial tuberculosis, it is not clear why pathologists failed to discover the changes characteristic of the condition at autopsy. Textbooks on pathology have been strangely silent with respect to this condition, which is now frequently reported from clinical sources.
