Ewing's sarcoma of the urinary bladder - the urologic and pathologic differential diagnosis and current therapeutic options.

The diagnosis of Ewing's sarcoma is identical to that of the other bladder tumors, i.e. transurethral resection. In the case of confirmation of this histological type, it is necessary to complete staging examinations and start multimodal treatment. Early systemic chemotherapy plays a key role and if metastatic spread is excluded, radical cystectomy or radiotherapy are included, too. The aim of our communication is to present a rare case of this disease, discuss the differential diagnosis and point out the principles and possibilities of its treatment.
