Rare presentations of Wilms tumor in children: A case report

Wilms tumor (WT) is the most common malignant tumor (neoplasm) of the urinary tract in early childhood. The median age at WT diagnosis is 3-4 years, and 90% of cases are diagnosed before the age of 7 years. In this report, three adolescent patients with WT, aged 12, 17 and 16, are investigated. Left kidney involvement was observed in these three cases. The clinical presentation in case one was the complaint of abdominal pain with a palpable abdominal mass. The second case was presented with hematuria and an abdominal mass. The clinical symptoms in case three included left flank pain and weight loss. Although WT is usually observed in children under 7 years of age, its diagnosis should also be expected in older children with abdominal pain, palpable mass and gross hematuria.
