This case report describes a 14-year-old boy with mandibular Ewing sarcoma treated with chemotherapy, hemimandibulectomy, and immediate titanium plate–stabilized chondrocostal graft reconstruction, with satisfactory function and facial symmetry and no recurrence reported at 6 months.
Research significance
The reported case provides preliminary evidence that chondrocostal autografting can achieve short-term mandibular reconstruction after Ewing sarcoma resection in a growing child; it may offer a growth-compatible reconstructive option, but comparative durability, safety, oncologic compatibility, and effects on craniofacial growth remain untested.
Source abstract
Ewing sarcoma is a rare malignant bone tumour that predominantly affects long and flat bones; mandibular involvement is exceptional. We report the case of a 14-year-old boy presenting with a firm, painless right cheek mass that progressively enlarged over 7 months. Clinical examination revealed a mass extending ~9 cm intraorally. The patient underwent surgical excision via vestibular hemimandibulectomy, followed by immediate reconstruction using a chondrocostal graft fixed to a titanium plate, alongside neoadjuvant and adjuvant chemotherapy. Histopathological and immunohistochemical analyses confirmed the diagnosis. At the 6-month follow-up, there has been no evidence of recurrence, and the patient has maintained satisfactory facial symmetry and oral function. This case highlights the importance of including Ewing sarcoma in the differential diagnosis of paediatric cheek masses and demonstrates that chondrocostal grafting is a viable reconstructive option in growing patients.
