Wilms tumor in Adult
Children most commonly present with an asymptomatic abdominal mass. Prior to diagnosis, 1 in 4 patients may develop a complication from tumor invasion of the kidney such as hematuria, abdominal pain, or hypertension. A small group can present more acutely in the setting of subcapsular hemorrhage with pain, rapidly enlarging abdominal mass, anemia, hypertension, and, in some cases, fever.
The majority of Wilms tumors are isolated lesions, with only 1 in 10 patients with multiple lesions in a single kidney and between 5%-7% with bilateral kidney involvement.
Wilms tumor has rarely been reported in adults. This summary focuses on children.
