Hepatoblastoma

Description

A malignant liver neoplasm that occurs almost exclusively in infants, although isolated cases in older children and adults have been reported. Grossly, hepatoblastoma is solid, well circumscribed, and more often solitary than multiple. Microscopically, most of the tumours are composed exclusively of immature hepatocytic elements. About a fourth of hepatoblastomas contain a stromal component that may be undifferentiated or develop into bone or cartilage.
