Scanning electron microscopic study of prostatic cancer.

Scanning electron microscopy is applied to the study of 3-dimensional surface and organization of a normal prostate gland and of samples of prostatic disease, including five cases of benign hyperplasia and 15 cases of prostatic adenocarcinoma of different degrees of differentiation. The study provided further evidence regarding the nature and origin of prostatic cancer at a cytologic level and indicated alternate pathways to the neoplastic spread within the prostate gland.
