Prostatic epithelial polyp diagnosed in a bladder wash.

ABSTRACT

Prostatic epithelial polyps, also known as adenomatous polyps or papillary adenomas with prostatic type epithelium, are uncommon lesions. These lesions typically involve the adult male urethra, trigone, or bladder dome. Diagnosis is usually made by biopsy. Presence of clusters of benign columnar cells in urine cytologic material can suggest the presence of such polyps and must be included in the differential diagnosis.
