The disease typically affects one side of an epiphysis (usually the medial side). Case presentation: A case in whom both the medial and lateral sides of the epiphysis were involved is described. Thus, the use of the descriptor “hemimelica” is not always appropriate. Conclusion: Although rare, Trevor's disease should be kept in mind during the differential diagnosis of patients with ankle pain and a mass. Other possible joints should be examined to explore multiple involvement. Surgical treatment, only on lesions causing impingements, may improve functional status and reduce pain. © 2018 Elsevier Ltdeninfo:eu-repo/semantics/closedAccessDysplasia epiphysealis hemimelica; Epiphyseal osteochondroma; Trevor's diseaseArticle36555810.1016/j.foot.2018.01.003303363402-s2.0-85054848642Q2
