Since the report on bronchial adenoma was presented by Wesler-Rabin in 1932 this problem has become a point of interest to many investigators, and among these the study on its histological features, histogenesis and malignancy by Foster-Carter is outstanding. However, there have been only 8 cases of bronchial adenomas reported in our country. The authors had the opportunity of examining the surgical material of a 28 yr. old male diagnosed as pulmonary tumor.<BR>Gross findings : Intrabronchial growth of tumor was found in the following branches ; Truncus bronchalis superior sinister, R. medius lateralis, R. medius sinister, R. apicalis ventralis. On the other hand, there is invasion of the tumor in the lung parenchyma with partial hemorrhage and necrosis. The above lesion is encapsulated by a fibrous tissue and the adjacent parenchyma is atelectatic. Bronchiectasis is found in the peripheral area andd colloid-like substance fills these cavities. The tumor is firm, milky white with hemorrhagic spots.<BR>Microscopical findings : The surface of the tumor showing intrabronchial growth is covered by normal bronchial epithelia, and necrosis and hemorrhage are sometimes observed. The tumor cells demonstrate the following arrangments : 1. solid-cord type, 2. Swiss-cheese-like adenomatous type and 3, papillary adenomatous type.
