Benign prostatic epithelial polyp of the urethra

Area of Science:

• Urology
• Pathology
• Oncology

Background:

• Acquired polyps in the male urethra are uncommon and can lead to symptoms like hematuria and hemospermia.
• The origin and differentiation of these urethral polyps have been a subject of ongoing debate in medical literature.

Observation:

• A case of a polyp in the prostatic urethra was identified and analyzed.
• The polyp presented with typical symptoms associated with urethral lesions.

Findings:

• Immunohistochemical analysis confirmed the polyp's origin from prostatic epithelial cells.
• The tumor cells within the polyp expressed prostatic acid phosphatase (PAP) and prostatic specific antigen (PSA).

Implications:

• This finding clarifies the histogenesis of certain prostatic urethral polyps.
• It suggests that prostatic urethral polyps should be considered a manifestation of prostatic epithelial differentiation.
