A 5 1/2-year-old child with hepatocarcinoma complicating hereditary tyrosinemia is presented. A review of the literature and an attempted follow-up of previously reported patients with the chronic form of hereditary tyrosinemia have disclosed 16 cases of hepatocarcinoma occurring in 43 patients surviving beyond 2 years of age (37%). This incidence is considerably higher than that generally given for the occurrence of hepatoma in adults with macronodular cirrhosis. Females and males are equally at risk. Additional factors beyond the development of cirrhosis are likely operative in the induction of hepatocarcinoma in patients with this metabolic disorder; those surviving beyond infancy are at considerable risk for the development of fatal hepatic neoplasms.
