Liver Neoplasms

Primary pediatric liver neoplasms are relatively rare, accounting for 5–6% of all intra-abdominal masses [1]. Malignant tumors are nearly twice as common as benign tumors in the pediatric liver, and these tumors account for slightly more than 1% of all pediatric malignancies [2–4]. The incidence of primary pediatric liver neoplasms varies by patients age but ranges from 0.4 to 1.9 per million children [1, 4].
