[Supernumerary liver. A case with a particular location in an omphalocele]

The authors report one case of a supernumerary liver lobe contained in the omphalocele of a new born. An accessory hepatic lobe was attached to the liver by a pedicle. Its histological structure was that of an immature liver. The authors review the different symptoms, varieties, and frequencies of supernumerary liver lobes. The importance of this embryological anomaly is underlined as it is normally latent and benign. It should be evoked whenever a radiological or palpable abdominal mass is discovered and in those cases where there are complications of unknown etiology.
