BACKGROUND Children with overgrowth syndromes including isolated hemihyperplasia have an increased risk for developing embryonal tumors, particularly Wilms' tumor and hepatoblastoma. Screening with sonography has been suggested as a method of identifying these tumors while they are still at an early stage. CASE PRESENTATION We describe an infant diagnosed with Wilms tumor in whom isolated hem...

Wilms' tumor is an uncommon neoplasm in adults. We report the clinical manifestations, complementary explorations, treatment, and results from 3 males aged 16, 21, and 22 years. Computed tomography commonly suggests the diagnosis. Despite its aggressive treatment, such as radical surgery, chemo- and radiotherapy, the prognosis is worse than in children.
