Ultrastructural aspects of human prostate in benign prostatic hyperplasia.

The ultrastructural morphology of the prostate in benign prostatic hypertrophy has been studied with particular attention focused on features of prostatic secretory processes and the formation of "corpora amylacea." Morphological and cytochemical comparisons of prostatic secretory vacuoles and multivesicular bodies have been carried out, and the secretory mechanisms of the prostate have been further defined by scanning electron microscopy.
