Primary hepatic tumours in children represent an heterogeneous group of neoplasms. Malignant tumours are more common (60% of primary liver tumours), but account for only 1.2-5% of all paediatric neoplasms. There are two main types of malignant tumour, those of epithelial origin, hepatoblastoma (HB) and hepatocellular carcinoma (HCC), and the rarer mesenchymal tumours, e.g. rhabdomyosarcoma and undifferentiated sarcoma, (Weinberg AG, Finegold, MJ. Primary hepatic tumours of childhood. Hum Pathol 1983, 14, 512-532). Vascular tumours e.g. haemangioendotheliomas are the most common of the benign tumours followed by mesenchymal hamartoma and the rare hepatic adenoma and focal nodular hyperplasia. This article will concentrate on the malignant epithelial tumours.

In this review we examine the diagnosis and treatment of pediatric liver tumors- both malignant and benign. The two most common malignant tumors are hepatoblastoma and hepatocellular carcinoma. Hepatoblastoma is seen in younger children, hepatocellular carcinoma in older children. Other malignant liver tumors are quite rare and include biliary rhabdomyosarcoma, angiosarcoma, rhabdoid tumor, and undifferentiated sarcoma. The commonly seen benign liver tumors in children are infantile hemangioma, mesenchymal hamartoma, and focal nodular hyperplasia. Rare benign tumors are hepatic adenoma, which is occasionally seen in teenage girls, and teratoma which is a very rare liver tumor in infants.
