Desmoplastic fibroma of mandible in a child: case report.

The aim of this report is to present a rare case of a child with a desmoplastic fibroma (DF) at the mandibular angle. This lesion commonly shows a radiolucent and radiopaque radiographic picture. Due to its aggressiveness and high recurrence rate, an early diagnosis is essential and the complete removal of the lesion is the treatment of choice. We present a case of 11-year-old boy who was referred to be treated for an growth in the left mandibular angle area, a radiolucent and radiopaque feature. After an incisional biopsy, the complete removal of the lesion was done without vascular or nerve damage of the inferior alveolar bundle and without causing mandibular discontinuity. The clinical and radiographic features suggested the diagnosis and allowed the differentiation of DF from other lesions in the maxillofacial area. However, the final diagnosis was only possible through histopathological examination.
