Which finding may be present in Wilms tumor?

• A. Abdominal pain and fever
• B. Hypertension
• C. Weight loss
• D. Jaundice

Answer: (B)

Hypertension is a classic finding in Wilms tumor because the tumor often secretes renin or disrupts renal vasculature, leading to increased renin–angiotensin–aldosterone system activity and secondary hypertension. This vascular effect is a characteristic clinical clue in pediatric nephroblastoma, helping distinguish it from other presenting symptoms. Abdominal pain with fever can occur but is non-specific for Wilms tumor. Weight loss can be seen with malignancy but is less characteristic here, and jaundice points toward liver or biliary disease rather than an intrinsic renal tumor.
