ACOSTA-GUALANDRI, Alejandra; PENON-PORTMANN, Mónica  e  QUESADA-RODRIGUEZ, Marco. Dysplasia epiphysealis hemimelica: Trevor disease. Acta méd. costarric [online]. 2015, vol.57, n.1, pp.49-51. ISSN 0001-6002.

We describe the clinical case of an 18-month old boy, evaluated at the National Children’s Hospital for difficulties in gait, with radiological findings of osteochondral overgrowth of the epiphysis of the proximal and distal tibia, astragalus and first metatarsal bone of the left leg. The patient was diagnosed with epiphyseal dysplasia hemimelica. Epiphyseal dysplasia hemimelica or Trevor´s disease is a non-hereditary osteo-cartilaginous defect. It affects the epiphysis and ossification centers, occurring predominantly in the lower limbs. Global prevalence is one in a million and its etiology is unknown. It is three times more common in boys than girls. Diagnosis is made through radiologic studies. Management options include clinical observation or surgery.

Palavras-chave : dysplasia epiphysealis hemimelica; Trevor’s disease; lower limb; epiphysis.
