Dysplasia epiphysealis hemimelica: two cases in two different regional expression.

Dysplasia epiphysealis hemimelica most commonly presents as an overgrowth of the epiphysis in the lower limb. We report two cases, one a classical form involving the lower limb, and the other in a relatively rarer location in the wrist. Both cases were treated surgically by excision of the masses. We recommend excision of symptomatic intra-articular lesions by using MRI, which provides additional information concerning physeal line and extension of the mass, to prevent the development of angulation and to keep the range of motion.
