Which is the most common pediatric primary liver malignancy?

• A. Hepatoblastoma
• B. Hepatocellular Carcinoma
• C. Fibrolamellar carcinoma
• D. Hemangiosarcoma

Answer: (D)

The question is testing which pediatric liver tumor is most commonly malignant. In children, hepatoblastoma is the most frequent primary liver cancer. It typically presents in very young kids (often under 3 years old) as a solid liver mass and is frequently associated with elevated alpha-fetoprotein levels. Imaging often shows a well-defined intraparenchymal mass that may contain calcifications; CT or MRI helps with characterization and staging. Other liver malignancies in children are much less common. Hepatocellular carcinoma can occur but is relatively rare in the pediatric population and usually happens in the setting of underlying liver disease. Fibrolamellar carcinoma is a rare variant of HCC seen in adolescents. Hemangiosarcoma is exceedingly rare in children and not a typical pediatric liver cancer. So the correct concept is that hepatoblastoma is the most common pediatric primary liver malignancy.
