Wilms tumor in adults. Report of a case

Wilms' tumor or nephroblastoma is the most common renal tumor of childhood. The incidence in adults is rare, estimated at about 1% of all cases and approximately 200 cases have been described in the world literature. We report a new case of adult Wilms' tumor and realize a short review. We describe a case of Wilms' tumor in a young male, aged 15 years, with associate genitourinary abnormalities. The patient underwent radical nepherctomy with postoperative chemotherapy. The Wilms' tumor in the adult population is exceptional, and the definitive diagnostic is based in the findings of the pathological analysis. The application of therapeutic protocolos for children to adults offers an smaller percentage of cure and poorer prognostic. Therapheutic protocolos more aggressive are necessary for increase the worse prognostic in the adult, but because of the rarity is difficult to define the most effective form of treatment.
