title: [Dyssegmental dwarfism. A new case].
abstract: In a 3 1/2 month old child with micromelic dwarfism, a case of dyssegmental dwarfism is reported. This affection is characterized, on one hand, by a shortening and a squat aspect of long bones with diaphyseal curve, and on the other hand, by a trouble of vertebral segmentation associated to a variability in the size of vertebral bodies. The differential diagnosis appears adequate to differentiate the dyssegmental dwarfism from other types of neonatal chondrodysplasia, in particular from Kniest syndrome and micrognathia dwarfism.
