In acute bacterial prostatitis, inflammation is observed in part or all of the gland. This is characterized by marked infiltration with neutrophils and diffuse edema. Microabscesses may be present, and these may coalesce into larger collections.

The histology of chronic bacterial prostatitis is that of focal, nonacute inflammation; however, this finding is not diagnostic, because it may be observed in men without bacterial infection. Because chronic bacterial prostatitis may be a focal disease, needle biopsies may be unreliable. Occasionally, biopsies reveal a granulomatous prostatitis of unknown cause.
