Hepatocellular carcinoma is an uncommon malignancy in young children a
ssociated with a variety of congenital and acquired conditions. It has
been generally held that idiopathic neonatal hepatitis is not an ante
cedent of hepatocellular neoplasia in childhood. We report a 28-month-
old girl in whom a diagnosis of neonatal giant cell hepatitis was conf
irmed by liver biopsy at 4 months of age who was followed up with seri
al liver biopsies. Hepatitis B and C virus infection and metabolic abn
ormalities had been excluded by appropriate testing. There was no hist
ory of parenteral nutrition. The morphologic criteria for a diagnosis
of cirrhosis were satisfied in a liver biopsy undertaken at 23 months
of age. At 28 months a laparotomy was performed because of continuing
jaundice and the development of an abdominal mass. Biopsy of the mass
revealed a hepatocellular carcinoma. Ploidy studies showed an aneuploi
d tumor and a hyperdiploid karyotype was confirmed by chromosomal anal
ysis. This case demonstrates by sequential biopsy the progression from
neonatal hepatitis to cirrhosis and hepatocellular carcinoma in a you
ng child.
