The histology of the dorsal, lateral, and medial prostatic lobes in man.

The light microscopic characteristics of the dorsal, lateral, and medial prostatic lobes were identified and described in an autopsy and an operative series of 73 and 21 males respectively. Ordinary histologic sections from anatomically defined prostatic lobes and gigant sections through the whole prostate were examined. Each of the three paired lobes had its own light microscopic characteristics. The gigant sections revealed the distribution of the separate lobes. Our findings emphasize that the human prostate cannot be looked upon as a homogenous organ.
