Childhood primary hepatocellular carcinoma is rare and accounts for less than 1% of all abdominal malignancies in children < or = 14 years of age. A review of the records of the Cancer Registry, Ibadan, Nigeria covering the period 1960-1995 was scrutinised and 19 cases of hepatocellular carcinoma (HCC) were registered, accounting for 0.49% of all abdominal malignancies over the period of review. The mean (SD) age at presentation was 10.4 (3.0) years and the duration of illness before presentation was short. All the children presented late with abdominal distension and hepatomegaly as the major clinical features. Weight loss was evident in 80% of cases, splenomegaly occurred in 50% and jaundice was present in a third of them. The prognosis was poor; all the cases died within 2 weeks of presentation in hospital. There was evidence to suggest an association between hepatitis B virus infection and HCC in all the liver tissue stained by Shikata-Orcein. This review shows that HCC, though uncommon, is important enough to be considered a possible cause of unexplained hepatomegaly in Nigerian children and that hepatitis B virus is an important aetiological factor. Though the number of cases under review is small, universal early vaccination against hepatitis B virus is necessary in Nigerian children in order to reduce the burden of chronic hepatitis B disease and hepatocellular carcinoma.
