Summary
A rare paraurethral leiomyoma, a benign smooth muscle tumor, caused urinary retention in a 44-year-old woman. Surgical removal was successful, restoring normal bladder function without recurrence.
Area of Science:
- Urology
- Gynecology
- Pathology
Background:
- Leiomyomas are typically found in the uterus but can rarely occur in the paraurethral region.
- Paraurethral leiomyomas are uncommon and can present with urinary symptoms.
Observation:
- A 44-year-old female presented with urinary retention due to a 9 cm paraurethral mass.
- Magnetic resonance imaging (MRI) confirmed the mass adjacent to the urethra.
- Transvaginal needle biopsy and subsequent surgical excision provided histopathological diagnosis.
Findings:
- The resected tumor measured 8 × 7 × 4.5 cm and weighed 194 g.
- Histopathology confirmed leiomyoma, with tumor cells showing estrogen and progesterone receptor immunoreactivity.
- The patient experienced an uneventful postoperative recovery with restored normal voiding function.
Implications:
- This case highlights the importance of considering rare pelvic tumors in the differential diagnosis of urinary retention.
- Surgical excision is an effective treatment for paraurethral leiomyomas.
- The hormonal receptor status may influence understanding of leiomyoma development and recurrence.
