Benign liver tumours

Only 1%–5% of all childhood neoplasms are primary liver tumours, from which the malignant ones are more frequent than their benign counterparts [1]. In contrast to malignant liver tumours, which are usually epithelial, most benign tumours are mesenchymal and derived from a supporting cell lineage leading to haemangiomas and MHs (Figure 17.1).
