Leiomyoma is a benign smooth muscle tumor which is rarely found in the paraurethral region. We report a case of paraurethral leiomyoma in a 44-year-old female who visited a clinic complaining of urinary retention. Magnetic resonance imaging revealed a 9cm mass adjacent to the urethra. She was referred to our department. Transvaginal needle biopsy was performed and the histopathological diagnosis was leiomyoma. The mass was completely excised transperitoneally and transvaginally. The resected specimen was 8×7×4.5cm in size and 194g in weight. Histopathological diagnosis was leiomyoma andthe tumor cells demonstrated immunoreactivity for estrogen receptors and progesterone receptors. Herpostoperative course was uneventful and she gained normal voiding function. In a follow-up after 3 months,  there was no evidence of recurrence. We discuss the clinical and pathological features of the paraurethral leiomyoma.
