Mesenchymal hamartoma of the liver in Beckwith-Wiedemann syndrome: The first reported case

The Beckwith-Wiedemann syndrome is a rare condition characterized by macros omia, macroglossia omphalocele, and visceromegaly. Although the development of neoplasia is frequent, the English literature has never described an as sociation with mesenchymal hamartoma of the liver. We report an exceptional case of Beckwith-Wiedemann syndrome associated with a cystic mesenchymal h amartoma of the liver in a newborn.
