Leiomyoma of the female urethra is a rare condition. We report one case of leiomyoma of the female urethra causing frequency, nocturia and dysuria. the differential diagnosis is caruncle, carcinoma, epithelial polyps or urethral prolapse. Transperineal ultrasonography reveals a 1.43 x 1.29 mm, well defined, round heterogeneous hypoechoic mass in the distal urethra. Color Doppler ultrasonography shows multifocal color signals in the peripheral and central portion of the mass. Histopathological examination confirmed urethral leiomyoma.
