Bronchoscopic diagnostic procedures and microbiological examinations in proving endobronchial tuberculosis.

Objective: To determine the proportional distribution of endobronchial tuberculosis (EBTB) subtypes and to evaluate the types of bronchoscopic diagnostic procedures that can prove granulomatous inflammation.

Methods: This was a retrospective study of 18 HIV-negative patients with biopsy-proven EBTB treated between 2010 and 2014.

Results: The most common EBTB subtypes, as classified by the bronchoscopic features, were tumorous and granular (in 22.
