Paraurethral tumor in females is a relatively rare disease. Herein, a case of paraurethral leiomyoma is reported. A 30-year-old woman consulted our hospital with complaints of a painless tumor and discomfort at the external genital parts. Local examination revealed a thumb's head sized tumor with smooth surface at the anterior wall of the external urethral meatus. Histologically, this tumor contained spindle cells and many collagenous fibers, and was diagnosed as leiomyoma. In Japan, there were 87 cases of female paraurethral benign tumor, which contained 47 cases of leiomyoma including this case. Fifty-four percent of the chief complaints for all female paraurethral tumors were palpable external genital masses; and, palpable painless mass was the most common complaint. Also, the patients with tumors of the posterior or lateral wall complained about urination more frequently.
