Introduction. Dysplasia epiphysealis hemimelica, also known as Trevor?s
disease, is an extremely rare skeletal developmental disorder of unknown
etiology, characterized by an osteocartilaginous outgrowth of one or more
epiphyses or of a tarsal bone during childhood. Case report. We presented a
sporadic case of dysplasia epiphysealis hemimelica developed in the talus. A
6- year-old boy complained of swelling of his right ankle joint, with painful
and reduced movements. Radiographies suggested excessive overgrowth of the
dorsomedial aspect of the talus. The tumor was surgically excised and the
gross and histological findings were consistent with those of osteochondroma.
Conclusion. Dysplasia epiphysealis hemimelica is diagnosed by clinical,
radiographic and histopathological examination. Early diagnosis is important
for the condition to be treated before the deformity becomes disabling.
