title: A morphologic study of nodular lung carcinomas and their possible pathogenesis from a cluster of non-obstructive bronchiectasis.
abstract: A very simple procedure has enabled us to show that nodular lung carcinomas correspond, to a high degree, to neoplasias arising in a cluster of bronchiectasis of the non-obstructive type. This pathogenesis explains their peculiar features: the round shape with a sharp borderline on the surrounding lung, the frequent cavitation, the prevailing histologic type of epidermoid carcinomas. At present, when thin-section CT allows discovery of bronchiectasis with no need for bronchography, this interpretation suggests the possibility of carrying out a prevention program which should consist of identifying the high-risk group of patients with bronchiectasis, 'sputum producers' and smokers, in which an early diagnosis of nodular lung carcinoma might be realized by periodical diagnostic cytology.
