Fibroma osificantea propósito de un caso. Revisión de la literatura

Abstract

Introduction: Ossifying fibroma is part of the group of fibro-osseus lesions. They are benign, but its essential feature is the replacement of regular bone tissue with collagen, fibroblasts and varying amounts of mineralized tissue. It usually occurs in women between third and fourth decades of life. It normally affects the jaw and can cause swelling in the area and rhizolysis of adjacent teeth. Treatment is based in a complete enucleation of the lesion. Case report: A 30 year old man comes to the oral and maxillofacial service after having previously been in the emergency service because of inflammation and swelling of the left mandibular region of a year of evolution. Radiological evidences show a radiolucent lesion with a sclerotic halo around. Final diagnosis after surgical excision was ossifying fibroma. Discussion: Ossifying fibroma is a fibro-osseus benign lesion, but it can cause deformity, displacement and rhizolysisof nearby teeth. For different radiographic patterns and being usually unilocular there is a large number of injuries that should be taken into account for a differential diagnosis; although in cases of multiple lesions, many are due to hormonal abnormalities such as hypercalcemia associated with hyperparathyroidism. Conclusion: The proper management is essential to make a differential diagnosis with other entities due to the different treatments that each condition requires.
