The literature on bronchial tumors is replete with arguments concerning the benignity or malignancy of bronchial adenomas. Similar allusions as to the unreliability of bronchial tumors of mesenchymal origin have been voiced.1 These discussions have centered around the various clinical as well as anatomical and pathological facets which are considered to be indicative of the behavior potential in such cases. As important as these considerations are, the final clinical outcome is the only ultimate measure of benign or malignant nature. We have thus studied our material, not only searching for the usual determinants of behavior potential but also considering as highly important the morbidity which these lesions can produce. For the purposes of this study we reviewed all the records of endobronchial tumor seen at the Veterans Administration Hospital wherein the neoplasm was not frankly carcinoma or sarcoma.
