Myxomas of the jaws are considered to arise from odontogenic ectomesenchyme. This pathology is most commonly found in young adults, but it may appear across a wide age group with an average age from 25 to 30 years with no sex predilection. We present a case of a 2-year-old male pediatric patient with the increased facial volume on the right side and six months of evolution without presenting symptoms, with the diagnosis of fibromyxoma, where a surgical resection through hemimandibulectomy with disarticulation and immediate costal graft reconstruction was performed. It was an uncommon case due to its extension and prolonged evolution time, which represented a challenge in our particular environment. Surgical resection may be required because myxomas are not encapsulated and, because of their consistency, they may infiltrate the surrounding bone. Long-term clinical and radiological follow-ups should be undertaken due to the risk of recurrence.
