Urethral leiomyoma: a rare presentation

Urethral leiomyoma: A rare cause of acute urinary retention

Introduction and importance

Leiomyoma is a benign smooth muscle tumor, which is the most common seen in the uterine and is rarely found in the urethra. These are benign mesenchymal tumors that arise from the smooth muscle, which appear during the reproductive age of a female. Diagnosis and management of this case at a rare location were discussed.

Case presentation

A 24-year-old woman with complaints of urinary retention and a mass protruding out of the urethral external meatus presented to the obstetrics and gynecology clinic. On pelvic examination, a red like mass was seen into urethral external meatus. Under local anesthesia, the patient underwent a basic excision of the urethral mass. Histopathological examination confirms the diagnosis of urethral leiomyoma.

Clinical discussion

Urethral masses are uncommon. The benign of which include urethral caruncle, Skene's duct cyst, Gartner's duct cyst, papilloma, hemangioma, and leiomyoma. After examination of the patient initial diagnosis was caruncle but after the pathology results showed leiomyoma.

Conclusion

Urethral leiomyoma is a rare benign tumor, which does require a histopathological examination for a definitive diagnosis despite being a benign formation. Urethral leiomyoma can be successfully removed with good outcomes.

•

Urethral leiomyomas are rare.

•

When urethral leiomyomas are seen they are usually proximal but we found a distal leiomyoma in this rare case.

•

Acute urinary retention after complete urethral blockage by a leiomyoma

•

Generally, no complications found after removal of distal urethral leiomyoma

Urethral Leiomyoma: A Rare Clinical Entity

Extrauterine leiomyomas are encountered occasionally, which can pose a diagnostic dilemma and challenge to the gynaecologist. We report a rare case of urethral leiomyoma. A 31-year-old woman with history of primary subfertility presented with mass at her urethral meatus and lower urinary tract symptoms. She underwent examination under anaesthesia and excision of the urethral mass. Histopathological examination confirmed leiomyoma. Diagnosis and management of this common growth situated at a rare location were reviewed and discussed.
