Giant ossifying fibroma of the mandible treated with en bloc resection and reconstruction plate placement in pediatric patient: case report and literature review

Abstract

Ossifying Fibroma is a benign fibro-osseous tumor, but osteolytic and invasive, as well as being a rare lesion. It manifests itself more frequently in the mandible than in the upper jaw, being located preferably in the molar (52%) or premolar (25%) region. It is most commonly diagnosed in women (5:1) between the 3rd and 4th decades of life. It is related to other pathologies such as bone dysplasia, florid cement-osseous dysplasia, among others. This lesion was called a tumor by the World Health Organization (WHO) in 1992 in its classification of Odontogenic tumors, because its possible etiopathogenesis is due to periodontal ligament cells. In 2003, the WHO called it a single entity, classified like a bone tumor. The following case that is presented is about a pediatric patient with a diagnosis of Ossifying Fibroma in the mandibular area of large size, which was treated surgically with an en bloc resection of the affected area due to the great extension of the lesion and the compromised tissue. and literature review.
