[Giant paraurethral leiomyoma in the female: a case report].
We report a case of giant paraurethral leiomyoma weighing more than 100 g in a 19-year-old woman. She had been complaining of micturition pain and a mass at the external genitals. Magnetic resonance imaging showed a 5 cm mass surrounding the urethra, which appeared low intensity on T1-weighted images and higher intensity than that of the surrounding muscles in the pelvis on T2-weighted images. Biopsy was performed and the pathological diagnosis was leiomyoma. The mass was removed transvaginally and transperitoneally, which did not invade to urethra or vaginal wall. The resected specimen exhibited 8 x 7.5 x 3.6 cm in size and 105 g in weight. Pathological diagnosis was leiomyoma with no invasion to surrounding tissue. This is the 132nd case of female paraurethral leiomyoma in Japan, and there were only five cases (6%) of giant paraurethral leiomyoma weighing more than 100 g. We discuss the clinical and pathological features of this disease.
