Benign bronchial tumors are encountered with considerable rarity. In 283 bronchoscopic examinations performed at the Veterans' Administration Research Hospital during three and a half years only 1 example of this lesion has been found. None has been found on 622 routine autopsies. During this same period 186 bronchogenic carcinomas have been discovered clinically or at autopsy. It is difficult to determine the over-all incidence of benign bronchial tumors from the recorded literature, but it is probably in the vicinity of 1% if one excludes the so-called "benign" bronchial adenoma.
Clinically the most prominent feature of a benign endobronchial tumor is bronchial obstruction. This may be accompanied by atelectasis or obstructive pneumonitis. A persistent cough, and occasionally hemoptysis, may precede or accompany the symptoms of bronchial obstruction. In the older age group the clinical diagnosis prior to endoscopy is usually bronchogenic carcinoma.
