'''Atrophy of the prostate gland''', also '''prostatic atrophy''', is a common change in the [[prostate gland]].  
'''Atrophy of the prostate gland''', also '''prostatic atrophy''', is a common change in the [[prostate gland]].  
It usually is seen focally; thus, it is sometimes called '''partial prostatic atrophy'''.

- Benign prostate tissue with glandular atrophy.

===Micro===
The core shows rare, spaced, atrophic appearing glands, mostly with a wavy border and a decreased quantity of cytoplasm. Prominent nucleoli and significant nuclear enlargement are not identified.
There are none of the following: mitoses, adjacent PIN, suspicious luminal material, nuclear hyperchromasia.
