A 71-year-old woman visited our hospital for routine follow-up cystoscopy and urine cytologic examination. During the preceding 3 years she had undergone left nephroureterectomy for a tumor of the left renal pelvis and had undergone transurethral resection three times for tumors of the urinary bladder and urethra. A small flare region on the posterior wall of the bladder was found with regular cystoscopy, and urine cytologic examination was positive for malignant cells. Computed tomography showed no distant metastasis and no right upper urinary tract mass. Transurethral resection was performed for the small flare region in May 2006. A papillary tumor of the vaginal wall was found incidentally during transurethral resection, and, therefore, transvaginal resection of the tumor was performed at the same time. Histologic examination of the excised genital lesion showed a G3 pT2 urothelial carcinoma, and the patient has been under observation since completion of external radiotherapy for the vaginal metastatic nodule.
