Mesomelic Dysplasia
Dr Alan Cameron 01 January 2001
Source: Platypus
If mesomelia is present, and in the absence of a family history of one of the particular types, the differential diagnosis includes a number of conditions whose description is beyond the scope of this text. Please refer to Taybi & Lachman (see references) for a more detailed description of these disorders.
In acromesomelic dysplasia the typical changes become more evident after birth, the tubular bones of hands and feet are very short.
Chondroectodermal dysplasia (Ellis-van Creveld syndrome) has mild to moderate mesomelia but the proximal and distal metaphyses are intact, there is congenital heart disease and polydactyly of the hands (99%) or feet (25%).
