[Freeman-Sheldon syndrome. Case contribution and review of the literature].

The paper reports a case of Freeman-Sheldon's syndrome in which a medium-slight degree of mental retardation which was not associated to malformations of the CNS was observed in addition to other typical symptoms. The presence of an hiatal hernia and vesico-ureteral reflow was also noted; to date it is still not possible to establish whether these visceral anomalies are chance findings or whether they are the result of a genetic defect involving tissues of different embryonal origin. Further studies are required to increase our knowledge of Freeman-Sheldon's syndrome and other nosologically related pathologies.
