The occurrence of hepatoblastoma is infrequent in children older than 5 years of age. Clinicians need to consider hepatoblastoma in school-aged children or adolescents presenting with multiple masses in the liver. A 10-year-old boy, who had no disease symptoms and malformations, suffered from anorexia and left hypochondrium pain for several weeks. He had a palpable stiff mass up to 5 cm below the right costal margin at the midclavicular line and tenderness in the upper abdomen. Laboratory examinations showed slightly elevated liver enzyme levels (AST/ ALT = 74/38 U/L; GGT = 38 U/L) and markedly elevated serum alpha-fetoprotein level (88 000 ng/mL). Ultrasonography revealed multiple bilobar tumors occupying the left liver and the right anterior section (Figure 1). Computed tomography

The occurrence of hepatoblastoma is infrequent in children older than 5 years. Therefore, clinicians need to consider hepatoblastoma even in school-aged children or adolescents.
