title: [A case of pure leiomyoma of the prostate].
abstract: A case of pure leiomyoma of the prostate is reported. This disease is very rare and only 10 cases could be collected from the Japanese literature. Our case is the 11th case of this disease in Japan. A 48-year-old man was admitted to our hospital because of urinary retention. Retrograde urethrocystogram showed evidence of protrusion of the left lobe of the prostate. Excretory urogram revealed bilateral hydronephrosis and voiding cystogram revealed VUR on left ureter. Transurethral biopsy suggested benign prostatic tumor. Open resection of the tumor was performed. Histologically, the specimen removed was pure leiomyoma of the prostate. After operative treatment, disturbance of urination and hydronephrosis disappeared.
