Aggressive Ossifying Fibroma of the Maxilla.

The aggressive ossifying fibroma is an uncommon benign fibro-osseous lesion which has been described in the literature under a variety of terms. This tumor is distinguished from standard ossifying fibroma based on its more clinically aggressive biological behavior, occurrence in children and young adults, and tendency to occur in different anatomic sites. We report a case of a 45-year-old female who presented with a unilateral swelling of the right middle face for 5 months. Clinical examination showed a mass extended over the right maxilla. Orthopantomogram and computed tomography scan were performed. Biopsy suggests a fibro-osseous lesion. The complete surgical excision of tumor was performed under local anesthesia. The histopathological examination revealed the diagnosis of an aggressive ossifying fibroma-trabeculae type. No recurrence was noted. Because of its aggressive and compressive nature, aggressive ossifying fibroma requires an early complete surgical excision. A long-term clinical and radiological surveillance is necessary to prevent recurrence.
