A 9-year-old boy came to our hospital because of intermittent gross hematuria. Bladder ultrasound showed a single papillary tumor on the posterior wall of the bladder, which was totally resected transurethrally. The histopathological finding was noninvasive papillary urothelial carcinoma. A follow-up examination revealed no recurrence 18 months after the surgery. Pediatric bladder cancer is extremely rare and our case is the 26th reported in the Japanese literature. In our total result, hematuria was seen in about 90% of cases, and pediatric bladder cancer tends to become low-grade tumors. TUR-BT was carried out in more than 70% of the patients. Our patient received VDC-IE chemotherapy for Ewing’s sarcoma at the age of 3, which might indicate late complications due to cyclophosphamide use. The number of these types of cases may increase because we will see an increasing number of long-term survivors after chemotherapy.
