Dysplasia epiphysealis hemimelica (DEH) is a developmental disorder with a very low incidence. It is
characterized by overgrowth of bone and cartilage in one or more epiphyses. The usual presentation of disease is
in a single limb and is hemimelic (involving either lateral or medial compartment). Lower extremities are more
frequently affected. Here we present a case of a male patient at 2.5 years of age presenting with bilateral
involvement of knee joints by DEH. The diagnosis was confirmed on both radiological and histopathological
findings.
