title: Focal nodular hyperplasia in an adolescent with glycogen storage disease type I with mesocaval shunt operation in childhood: a case report and review of the literature.
abstract: As patients with glycogen storage disease type I survive longer, cases with hepatic tumor have been increasingly documented. A 16 year old boy with glycogen storage disease type I was evaluated for multiple liver tumors. He was diagnosed on clinical features at 9 months of age and underwent a mesocaval shunt operation at 5 years of age. The biopsy of one of the masses showed focal nodular hyperplasia. This is uncommon in patients with glycogen storage disease type I, compared to those with adenoma or malignant hepatic tumor. The association of a portacaval shunt with focal nodular hyperplasia is significant compared to other tumors. An environment of high estrogen concentration or sex hormone binding globulin accompanied by shunt operation may cause focal nodular hyperplasia to develop in the liver of patients with glycogen storage disease type I.
