Nodular Hyperplasia of Prostate
This was an autopsy specimen from a man aged 70 who died following myocardial infarction.
The specimen is a bladder and urethra opened from the anterior aspect to display the mucosal surface. The bladder mucosa is thickened and congested and there is considerable muscular hypertrophy of the bladder wall. The prostate is enlarged and a prominent median lobe projects into the floor of the bladder in the region of the trigone. This is an example of benign adenomyomatous hyperplasia of the prostate with associated bladder wall hypertrophy and cystitis resulting from urinary obstruction.
