Dysplasia epiphysealis hemimelica in a Boxer puppy.

A Boxer puppy had an unusual dysplastic lesion of the distal epiphysis of the left femur. Biopsy and CT examination were performed. A diagnosis of dysplasia epiphysealis hemimelica (DEH) was made. To the investigators knowledge, this condition has not been described before in animals. DEH is a growth disorder involving preferentially the medial compartment of the lower limbs, and it is associated with epiphyseal hypertrophy and delayed mineralization.
