Case Report and Review of Recurrent Dysplasia Epiphysealis Hemimelica After Surgery

This article is a case report combined with a review of the literature on Dysplasia Epiphysealis Hemimelica (DEH), focusing on recurrence after surgical intervention. The authors present a single patient who experienced recurrence of DEH 3 months following initial surgery, with symptoms including increased pain, limping, and significant ankle stiffness compared to the initial presentation. Histopathological examination of the recurrent lesion revealed immature fibrocartilaginous tissue, nodular proliferation of collagenous fibrous tissue, cartilage fragments, and foreign-body granulomatous reaction.

The authors note that recurrence in DEH is closely linked to incomplete surgical excision and the patient's age. Based on this single case and review, they propose a postoperative follow-up protocol to mitigate the risk of recurrence. However, the evidence is limited by the nature of a single case report, and generalizability beyond this case is not possible.

No adverse events or safety data were reported. The practice relevance is limited to suggesting a follow-up protocol, but clinicians should recognize that these findings are derived from a single case and literature review, not from a controlled study.
