Prostatic-type polyp is an uncommon polyp of the genitourinary tract. It is typically centered on the verumontanum of the prostate gland and projects into the urethra.
General
- Hematuria - classic presentation.[1]
- Uncommon - as a separate specimen.

Features:[2]
- Benign prostatic type epithelium or transitional type epithelium.
- Cuboidal to low columnar cells with basal cell layer.
- +/-Corpora amylacea.
