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.
