Wilm's tumor in adult: case report

Abstract

Wilms' tumor is the renal tumor with the higher incidence on the childhood, however it rarely occurs in adults. The incidence in this group is estimated at about 1% of all the cases and they have an obscure prognosis. In this report is related a new case in a 52 years old man presenting intensive abdominal pain associated by weightiness. Abdominal ultrasound revealed expansive and complex lesion with indefinite contour in the left flank. Computed tomography of abdomen demonstrated solid lesion on antero-superior pole of the left kidney invading para-vertebral musculature, peri and para-renal spaces. Total nephrectomy and the histopatologic analysis were realized. A nephroblastoma (Wilms' tumor) in estage II without anaplasia was diagnosed by the anatomopatological studies. Local radiotherapy was applied. Thereafter was diagnosed pulmonary and hepatic metastasis, and then initiated the chemotherapy with adriamycin, actinomycin and vincristine. The prognosis of Wilms' tumor is worse in adult and it requires an aggressive therapeutic and follow up.
