A week before admission, a boy 3 years 3 months of age was referred to our clinic because his abdomen was large and a huge abdominal mass was palpated by his physician.

On admission, the child's height was 96.5 cm, and he weighed 15.9 kg. He seemed to be in good health although his abdomen was greatly distended. His temperature and blood pressure were normal, as were the results of the rest of the physical examination, excluding the abdomen. Palpation of the abdomen showed a large mass that was soft and nontender; its margins were not discrete. No organs were palpable, and there was no edema.

Hemoglobin level, leukocyte and differential cell counts, urinalysis, and roentgenogram of the chest were normal. The levels of urinary vanillylmandelic acid and homovanillic acid were normal. The serum level of creatinine was 0.45 mg/dL. Values for electrolytes, alkaline phosphatase, SGOT, and SGPT were normal.
