Pure leiomyoma of the prostate is very rare. A 67-year-old man was hospitalized with gross hematuria and urinary retention. Drip infusion pyelography revealed a defect of the urinary bladder. By radiological examinations, submucosal tumor of the bladder neck was diagnosed. Transrectal biopsy suggested a benign prostatic tumor histologically. Open resection of the tumor was performed. Histological findings were pure leiomyoma of the prostate. The postoperative course was good and urinary retention was improved remarkably.
