ABSTRACT
Eleven patients with proved Bronchiolo-aveolar cell carcinoma were found in the chest department of thenational menical center from 1975 to 1981. The incidence of Bronchiolo-alveolar cell carcinoma is recentlyincreased as primary lung carcinoma. The result as follow. 1. The ratio of male and female was 5:6 and anincidence of 4.4% among total primary lung cancer patients. The highest incidence (3 of cases) was seen in thesixth decade, and the remaining cases were evenly distributed in the third, fourth, and fifth decades of life.Among them youngest was 29 years old and the oldest was 66 years old. 2. Clinical and radiological initialdiagnosis prior to the final diagnosis were as follows; pulmonary tuberculosis; 7 cases, pneumonia; 1 case,bronchiectasis; 1 case, and lung cancer; 2 cases. 3. Radiological examination of chest presented several pictures;most commonly, homogenous or patchy infiltrations; 6 cases, nodular or mass like densities; 2 cases, disseminatednodular or military patterns; 2 cases, and reticular pattern; 1 case. 4. Bronchogram reveald no contributablefindings except one case of complete tappering obstruction of the segmental bronchus. Therefore we arrive at theconclusion that early diagnosis will result in increased resectability and improved survival so aggressivediagnositic work-up for suspicious pulmonary infiltrate is necessary.
