[The Fanconi-Bickel syndrome: one more case].

The association of de Toni-Debré-Fanconi syndrome with alteration of galactose metabolism and glycogen hepatic storage, before further clarification, is defined as Fanconi-Bickel syndrome. The Authors present a case in which the alterations in galactose metabolism typically do not affect the enzymes responsible for galactosemia. In such patients a recognised enzymatic defect glycogenosis is not involved and glycogen storage in the liver can be a secondary phenomenon, which can increase, differing according to each subject. Liver biopsy to detect storage can be avoided when all the other diagnostic criteria are observed.
