PURPOSE Dysplasia epiphysealis hemimelica (DEH) is a rare developmental disorder resulting in epiphyseal overgrowth. Based on histological appearance, it is often described as an osteochondroma or osteochondroma-like lesion, although clinical differences exist between DEH and osteochondromas. The aim of this study was to test whether DEH and osteochondromas are histologically identical diseases...

© 2005 Canadian Medical Association D epiphysealis hemimelica (DEH), also known as Trevor’s disease, is a rare developmental disorder affecting the epiphyses; in young children, it usually involves the knee and ankle joints. DEH was first reported by Mouchet and Belot in 1926, who named it tarso megalia. In 1950, Trevor used the term tarso-epiphyseal aclasis. Fairbank in 1956 coined the term dy...

Dysplasia epiphysealis hemimelica (DEH) or Trevor's Disease is a very rare disease with an estimated incidence of one in 1.000.000. The majority of cases reported affect the lower limb and only 25 case reports of 33 cases with affection of the upper limb have been published. Here we present a case of DEH affecting the distal ulnar epiphysis and the lunate in an eleven-year-old girl, a DEH locat...

Dysplasia epiphysealis hemimelica, also known as Trevor's disease, is a rare developmental disorder with osteocartilagenous overgrowth of the epiphysis or epiphyseal equivalent. The condition bears similarities to osteochondroma in terms of its radiographic appearance, but differs in its pathobiology and geographic occurrence. Unlike the metaphyseal occurrence of osteochondromata, it arises fro...
