Q1 :
Amother brings in her 3-year-old girl because she felt a smooth mass on the left side of her belly when she was giving her a bath. Which of the following is the most likely diagnosis?
(A) Wilms tumor
(B) neuroblastoma
(C) acute lymphoblastic leukemia
(D) Hodgkin’s disease
(E) hepatoblastoma
Answer
(A)
Wilms tumor is a malignant embryonal neoplasm of the kidney. It is the second most common solid tumor of childhood. Girls are affected more frequently than boys (2:1). The incidence of Wilms tumor peaks at 1–3 years of age.
The classic presentation is a painless abdominal mass that is usually hard, smooth,and unilateral. Hematuria occurs in 12–25% of children with Wilms tumor, and hypertension has been reported in up to 60% of patients.
Aniridia or hemihypertrophy may be observed in patients with Wilms tumor.
