Fibroepithelial Polyp

Clinical Notes

Surgery – Filiform polyp arising from the veru montanum.

Pathology – Ulcerating/granulating squamous epithelium covering a fibrovascular stroma with occasional smooth muscle bundles.


US – Hypervascular filiform soft tissue mass protruding into the urinary bladder.

VCUG – Urinary bladder filling defect emaninating from the urethrovesical junction.


Urethral polyps are a rare anomaly of the male urethra. Most commonly these originate from the veru montanum. Presenting symptoms include urinary retention, incomplete voiding, urgency, and hematuria. Etiology is controversial; congenital, inflammatory, and traumatic theories have been proposed. Differential diagnosis includes blood clot, cystitis cystica, papilloma and other mucosal disorders. Surgical excision is curative.
