A case of bilateral dysplasia epiphysealis hemimelica associated with polydactyly and syndactyly.

Abstract

Dysplasia epiphysealis hemimelica (DEH) on bilateral medial malleoli occurred in a boy who had polydactylies and syndactylies of all four limbs. Cases with both bilateral and symmetrical DEH affection as in this case seem not to have been reported previously in the literature. Dysplasia epiphysealis hemimelica complicated by congenital anomalies is extremely rare. A one-month-old boy of normal delivery had polydactylies of thumbs, small fingers, and great toes, and had symmetrical syndactylies of fingers and toes. At age eight, the patient reported swelling and tenderness on bilateral medial malleoli. Radiographs showed small blotches of radiopacity. Two years later, the radiopacities had enlarged to become typical of DEH.
