LOCALLY ADVANCED BLADDER EWINGS SARCOMA: AN EXCEPTIONAL CASE REPORT

Extra skeletal Ewings sarcoma is a rare entity. The primary bladder localization is exceptional, their diagnosis is difficult because it is extremely rare in this place and because of diagnostic difficulties posed by a group of very heterogeneous tumors. Its clinical presentation is similar to that of transitional cell carcinoma, however the two entities must be distinguished because the protocols for treatment are different. The diagnosis is dependent on the pathological examination with the immunohistochemical and cytogenetic study. We report the case of a 36-year-old man with locally advanced Ewing sarcoma of the bladder.
