概要	Ewing sarcoma (ES) of the bladder is extremely rare. Here we report the successful treatment of the youngest case of ES arising from bladder encountered to date and a literature review. A 10-year-old boy who presented with polyuria and lower abdominal swelling was found to have a 13 cm mass arising from the bladder localized to the center of the lower abdomen. Biopsy confirmed ES. Following chemotherapy, the mass shrank to 5 cm and was found to be localized to the right side of the bladder with invasion of the right vas deferens. One-third of the right side of the bladder and part of the right vas deferens were resected. No viable cancer cells were detected in the resected specimen, and the surgical margins were reported to be negative. The patient is currently well with no recurrence or metastases after 11 months. There are 12 cases of Ewings sarcoma arising from the bladder reported in the English literature; two cases in children. Our case will be the third pediatric case and the youngest.
