Which tumor is the most common malignant liver tumor in children aged three years or younger?

• A. Hepatoblastoma
• B. Hepatocellular Carcinoma
• C. Neuroblastoma with Hepatic Metastasis
• D. Wilms Tumor with Liver Metastasis

Answer: (A)

In children three years old or younger, the liver tumor that most commonly arises as a primary liver cancer is hepatoblastoma. This tumor typically appears in the first few years of life and often presents as a rapidly enlarging abdominal mass, usually in the right upper quadrant. Serum alpha-fetoprotein levels are frequently markedly elevated, which helps distinguish it from other masses. Imaging and histology confirm the diagnosis, and treatment generally involves chemotherapy to shrink the tumor followed by surgical resection when feasible; prognosis depends on resectability and extent of disease. Hepatocellular carcinoma is far less common in this age group and usually occurs with underlying liver disease or in older children and adults. Neuroblastoma or Wilms tumor can involve the liver, but in those cases the liver lesion is a metastasis from a tumor originating elsewhere, not a primary liver cancer.
