A morphologic study of nodular lung carcinomas and their possible pathogenesis from a cluster of non-obstructive bronchiectasis.


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… (More)
