mandibulectomy

Desmoplastic fibroma (DF) is a rare benign but aggressive fibrous lesion with an unknown etiology. It has an affinity for the mandible. DF has a high rate of recurrence after surgical resection. In this study, we report the therapeutic management of a recurrence of DF in the lower jaw in a 2‑year‑old boy. He responded well to second surgical intervention with wide resection and immediate reconstruction with plate. The purpose of this case report is to emphasize the particularity of the case, treatment modalities, and differential diagnosis in DF.
