Abstract:
Reported are two cases of benign endobronchial lesions with granulomatous reactions that led to complete airway obstruction. Combined with a long history of cigarette smoking and the appearance of a hilar mass, these lesions appeared clinically to be bronchogenic carcinomas. Both cases went to thoracotomy, but in each case the requirement that malignant tissue be identified, allowed recognition of a foreign body in one case, and broncholith in the second, avoiding pneumonectomy in both cases.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
