[Familial childhood cortical hyperostosis]

We present three cases of Caffey's disease, which have been observed in a family and a previous one former generation of the same family. A review of the literature upon family cases is carried out (35 families with 143 patients) prevailing the hypothesis of the type of autosomal dominant trait with incomplete penetrance and variable expressivity. HLA system is studied in such a family without common haplotypes being found and therefore the trait does not seem to be linked to genes of this system.
