Desmoplastic Fibroma of the Mandible in a Pediatric Patient: A Case Report of Resection and Reconstruction With A Six-Year Follow-Up

Desmoplastic fibroma (DF) of bone is considered a benign but locally aggressive tumor of fibroblastic origin. DF is rare, representing less than 1% of all bone tumors. Approximately 84% of patients are younger than 30 years. DF has a slow but aggressive growth potential and can recur locally when it has not been completely excised. Complete resection is the treatment of choice to decrease recurrence and morbidity. Mandibular reconstruction is mandatory in pediatric patients to ensure correct craniofacial development. The present report describes the case of a pediatric patient with mandibular DF in whom complete resection and immediate reconstruction with a fibula flap proved a satisfactory treatment option, with low morbidity and excellent esthetic and functional results at 6-year follow-up.
