Wilms tumor in adult

Wilms Tumor (WT) is a very rare malignancy in adults representing 1% of all renal neoplasms. It is however the most common renal tumor of children and adult patients are treated like pediatric cases. Bilateral tumors occur in 5% of adult cases. The typical presenting features are asymptomatic abdominal mass (most common), hematuria, pain, fever, and hypertension. As clinical presentation of WT is similar to that of renal cell carcinoma (RCC), it tends to be an unsuspected pathological diagnosis in most cases. The diagnosis of the tumor needs positive sonographic and computed tomography (CT) findings with histopathological confirmation. Prognosis of adult WT is relatively poor and resistant to chemotherapy. We present a case of wilms tumor in a 68 years old male patient with right sided non tender abdominal mass and occasional flank pain. The patient was normotensive but hematuric and radiological findings suggested right renal mass with enlarged lymph node and histopathological analysis revealed nephroblastoma associated with lymph node metastases.
