Upper airway obstruction due to tuberculosis. Treatment by photocoagulation.

We describe here a case of endotracheobronchial tuberculosis involving both the trachea and major bronchi. Endobronchial carcinoma was suspected initially, even at the time of bronchoscopy. Later, despite improvement of the pulmonary infiltrate and clinical symptoms after chemotherapy, upper airway obstruction occurred. Repeat bronchoscopy showed a distal tracheal nongranulomatous, fibrogranular stenotic lesion. Laser therapy was then employed to reduce the stenosis.
