RESUMO
We experienced a case of 67-year-old female with leiomyoma of the urinary bladder accompanied with voiding difficulty. Patient evaluation included IVP, ultrasound, pelvic CT scan and cystoscopy with biopsy. She had a tumor at anterior wall of the urinary bladder and the mass lesion of left ovary. The urinary bladder tumor was removed by partial cystectomy and the mass of left ovary was removed by total abdominal hysterectomy and lect salpingooophorectomy, simultaneously. Microscopically, the tumor of the urinary bladder had spindle shaped nucleus, polychromasia without mitotic figure, and was confirmed as the benign leiomyoma. The tumor of the left ovary was diagnosed as the thecoma on its histologic examination. The leiomyoma is an uncommon benign tumor of the urinary bladder. We report a case of leiomyoma of the urinary bladder with review of the literature.
