|Abstract:||Out of 150 prostatectomies, 129 cases were chosen for microscopic examination of the removed specimens. In this study a nodular lesion was defined as such showing a clearcut boundary from and distinct pressure upon its surroundings. In two specimens, no nodular lesion was found. The nodules were classified, according to their size, into three types: the small type with the maximum diameter being less than 0.4cm, the middle type from 0.5 to 0.7cm, and the large type more than 0.8cm. More than 40 % of the nodules belonged to the middle type. Small number of the large type nodules might be explained by their loosing morphological characteristics due to some causes. Regardless the size of the prostate, the ratio of each nodule type in the specimens was almost same. In the big prostates, however, the extranodular tissue showed more advanced degenerative changes such as atrophy and cyst formation than the nodular tissue itself did.|
