We present a case of rhizomelic dwarfism with clinical, radiographic a
nd histologic features in keeping with atelosteogenesis type III (spon
dylohumerofemoral hypoplasia). Unlike most other skeletal chondrodyspl
asias presenting with neonatal dwarfism, a proportion of patients with
atelosteogenesis type III may survive well beyond the neonatal period
, and hence early identification of the condition is important. Our su
rviving patient further defines the radiographic features of the condi
tion and the natural history and prognosis for physical and intellectu
al disability.
