[A case of leiomyoma of the urinary bladder associated with transitional cell carcinoma].
We report a case of leiomyoma of the urinary bladder associated with transitional cell carcinoma. A 60-year-old-male was referred to our hospital because of the complaint of dysuria and for detailed examination of left hydronephrosis. Drip infusion pyelography revealed left uretero-vesico junction stenosis. Flexible cystoscopy revealed benign prostatic hypertrophy and epithelial bladder tumor at the bladder neck and left ureteral orifice. The tumor was histologically diagnosed as TCC (transitional cell carcinoma). M-VAC chemotherapy (methotrexate 30 mg/m2, day 1, 15, 22, vinblastine 3 mg/m2, day 1, 15, 22, adriamycin 30 mg/m2, day 2, cisplatin 70 mg/m2, day 2) was performed as a neoadjuvant chemotherapy. However, since pelvic MRI revealed tumor invasion in to the muscle area, total cystoprostatourethrectomy and ileal conduit were done. Pathological examination of the tumor of left ureteral orifice revealed TCC, G2, INF beta, pT1, ly0, v(-), pN0, PM0. The tumor in the bladder neck was histologically diagnosed as submuscosal type leiomyoma. No cases of leiomyoma of the urinary bladder associated with transitional cell carcinoma have been reported in Japan.
