Adult Wilms' Tumour: A Rare Presentation of Two Case Reports with Review

Nephroblastoma (Wilms’ tumor) the most common malignant renal tumor in childhood, is extremely rare in adults. The diagnostic is usually made by pathologic examination of a surgical specimen. Despite its aggressive treatment, such as radical surgery, chemo and radiotherapy; prognosis of nephroblastoma in adults is worse than in children. The authors report the clinical manifestations, complementary explorations, treatment, and results of two cases of nephroblastoma incidentally diagnosed in adult age. We conclude that the possibility of an adult Wilms’ tumor should be considered when a patient presents with pain in the flank and a renal mass.
