Urological research·2001

A rare urethral polyp with prostatic-type epithelium caused urinary issues in a man. Recurrence after resection confirmed this unusual prostatic urethral condition.

Area of Science:

Urology
Pathology

Background:

Chronic prostatitis can present with obstructive urinary symptoms.
Urethral tumors are uncommon causes of lower urinary tract symptoms.

Observation:

A 38-year-old man presented with difficult and frequent urination, initially diagnosed as chronic prostatitis.
Imaging and urethroscopy revealed a urethral tumor in the posterior urethra, diagnosed as a urethral caruncle.
The tumor recurred as a urethral polyp after initial resection.

Findings:

Pathological examination of the recurrent polyp revealed prostatic-type epithelium.
Staining with anti-prostatic acid phosphatase antibody confirmed the prostatic origin of the epithelium.
The final diagnosis was a polyp with prostatic-type epithelium in the prostatic urethra.

Implications:

This case highlights a rare entity of prostatic-type epithelium presenting as a urethral polyp.
Such lesions can mimic or coexist with chronic prostatitis, complicating diagnosis.
Further research may be needed to understand the etiology and optimal management of these rare urethral growths.
