Recurrent dysplasia epiphysealis hemimelica of the ankle in a child requiring three surgical excisions over five years

Dysplasia epiphysealis hemimelica, also known as Trevor’s disease, is a rare developmental disorder characterized by asymmetric epiphyseal osteochondral overgrowth, most commonly affecting the ankle or knee in pediatric patients. Surgical excision is typically indicated when lesions cause deformity, mechanical symptoms, or functional limitation, although recurrence has been reported. We present the case of a three-year-old male with dysplasia epiphysealis hemimelica of the ankle who experienced two recurrences over a five-year period despite apparently complete surgical excision confirmed intraoperatively. The patient ultimately required three operative procedures due to progressive gait disturbance, stiffness, and pain with ambulation. This case demonstrates the potential for repeated recurrence in skeletally immature patients and highlights the importance of symptom-guided management and long-term surveillance in pediatric patients with dysplasia epiphysealis hemimelica.
