Bronchial Adenomas are rare entity among the primary bronchopulmonary neoplasms. But they have received attention because of debate on their malignant nature, prognosis, and mode of therapy. We have four carcinoids and two cylindromas from Jan. 1972 to Jun. 1983. Operations include two pneumonectomies two lobectomies and one bilobectomy. In one cylindroma, resection was impossible due to its invasion into mediastinum and pericardium. There were no hospital deaths.
