Dysmorphic Syndromes and Constitutional Diseases of the Skeleton is a large diagnostic atlas, which includes 400 dysplastic and dysmorphic syndromes in which the skeletal apparatus may be constantly or frequently involved. The initial chapter gives a critical account of the problems concerning the classification of the constitutional diseases of the skeleton. It is followed by the description, in alphabetical order, of the various diseases and syndromes. After definition, synonims are listed, aetio-pathogenesis, risk of recurrence, incidence, sex incidence, age when diagnosis can be made, Clinical and radiological pictures are subdivided according to organs and systems involved, distinguishing the common from the less frequent signs. The same occurs for laboratory investigations. Anatomical and histological descriptions follow, then prognosis and discussion of the diagnosis (specific, differential, prenatal, carriers) and finally therapeutic indications and a comprehensive bibliography. The iconographic documentation is mainly original and very ful, as this is principally a diagnostic atlas, including 1154 composite illustrations for a total of 3997 pictures (clinical, radiological and anatomo-pathological) dealing with various patients at different age periods.
