[Desmoplastic fibroma of the skull in an infant].

Desmoplastic fibromas are uncommon osseous tumors that seldom involve the skull. These tumors are histologically benign but locally aggressive with a propensity for recurrence if resection is partial. To our knowledge, only 16 cases have been reported in the literature, seven of which concerned children. We report a further case of a desmoplastic fibroma of the skull in a 3-year-old boy who presented with a right parietal mass. The CT scan showed a lytic mass with brain compression and cortical destruction. The patient underwent a craniectomy and complete mass resection. Histological diagnosis was desmoplastic fibroma. Postoperative progress was normal without recurrence 6 months later.
