The patient was a 42 year-old woman with uterine myoma who had pain on micturition. Cystoscopy showed a broad-based tumor covered with edematous bladder mucosa about 20 mm in diameter at the left anterior bladder wall. Transurethral ultrasonography of the bladder and transabdominal ultrasonically guided biopsy of the entire layer of bladder wall were performed. The preoperative diagnosis was leiomyoma of the urinary bladder, and partial cystectomy combined with simple hysterectomy was performed. Primary leiomyoma of the urinary bladder was confirmed by histopathological diagnosis obtained from the excised specimen.
