Type 1a glycogen storage disease with hepatoblastoma in siblings.
Clinical and histologic details of the two siblings with type 1a glycogen storage disease (GSD-1a) who developed hepatoblastoma are presented. The light microscopic studies on hepatic tumor in both siblings revealed fetal type of hepatoblastoma. Ultrastructural findings in Patient 2 showed markedly altered mitochondria, which were frequently surrounded by the rough endoplasmic reticulum. This is the first known occurrence with this association, and the third report on the familial occurrence of this neoplasm. Glycogen storage disease may increase the risk of hepatocellular carcinoma and hepatoblastoma.
