Wilms tumor is the most common renal solid mass and abdominal malignancy of childhood. Although Wilms tumor is a malignant tumor, the prognosis is excellent with a 5-year survival rate of 90%, and 70% for metastatic disease.
The classic Wilms tumor´s presentation is usually a solitary lesion in a kidney and there is usually no metastasis at the time of diagnosis. Although the disease can develop lung metastases, liver and rarely in bone and brain. However, there are other atypical forms of Wilms tumor presentation as a bilateral tumor, multifocal tumor, metastatic disease at diagnosis, intravascular tumor, pulmonary and abdominal relapse in which the survival rate and the success of the therapy can be compromised.
