Abstract

Dysplasia epiphysealis hemimelica is a rare developmental disorder with unknown etiology affecting epiphysis mostly in childhood. Dysplasia epiphysealis hemimelica is usually considered an intra-articular variant of an osteochondroma owing to its presenting symptoms and histologic findings. Surgical treatment is mandatory when symptoms such as pain, joint impingement, or deformity are present and will yield good results when the mass is juxta-articular or extra-articular. In those cases in which the mass is intra-articular and surgical intervention could affect the growth of the epiphysis, surgical treatment should be carefully evaluated and considered. A case of recurrence of dysplasia epiphysealis hemimelica located in the distal tibial epiphysis and talus that was successfully treated with surgery is presented.

Case Report

We present the case of a patient, a 3-year-old male, who was referred to the Second Xiangya Hospital of Central South University for evaluation of a mass at the posteromedial aspect of his left ankle. The mass was not associated with pain but had been slowly enlarging for 3 months. He had a history of an obvious deformity and an abnormal gait for which he had undergone operative excision at a local hospital when he was 1 year old. Osteochondroma of the left ankle had been diagnosed. He had no

Discussion

DEH was originally described as tarsomégalie by Mouchet and Belot (8) in 1926. Subsequently, in 1950 and 1956, Trevor (9) and Fairbank (10) used the term tarso-epiphyseal aclasis and dysplasia epiphysealis hemimelica, respectively, to identify this uncommon skeletal developmental disorder. The reported prevalence of DEH has been 1 in 1,000,000, with male children affected up to 3 times more frequently than female children (11). The etiology is still unknown.

DEH typically involves 1 or several
