Une tumeur maxillaire à ne pas méconnaître : le fibrome ossifiant de type juvenile

Juvenile ossifying fibroma: case report and literature review. Management and differential diagnosis

Introduction: Juvenile ossifying fibroma (JOF) is a rare neoplasm characterized by the replacement of the normal bone matrix with osteo-fibrous tissue. It has the tendency to be locally aggressive despite its benign character and to have a strong tendency for recurrence. Observation: In this case report, the patient is a young man, aged 16, with rapidly advancing maxillary swelling. We describe the diagnostic procedure, the surgical procedure and the differential diagnosis to be eliminated. Discussion: The clinical presentation of JOF, and its rapid growth, can cause fear of other pathologies such as osteosarcoma. The radiological characteristics should reassure the practitioner and a histological examination confirmed the diagnosis. Conclusion: JOF is a benign tumor. It should be operated on at an early stage because of its rapid growth. In its clinical and histological presentation, its trabecular form may mimic an osteosarcoma.

Diagnosis and management of benign fibro-osseous lesions of the jaws: a current review for the dental clinician

Benign fibro-osseous lesions of the maxillofacial skeleton constitute a heterogeneous group of disorders that includes developmental, reactive (dysplastic) and neoplastic lesions. Although their classification has been reviewed multiple times in the past, the most common benign fibro-osseous lesions are fibrous dysplasia, osseous dysplasia and ossifying fibroma. For the dental clinician, the challenges involve diagnosis and treatment (or lack thereof). A careful correlation of all clinical, radiologic and microscopic features is essential to establish a proper diagnosis and a clear treatment plan. This article aimed to review the clinical, radiologic and histopathologic characteristics of benign fibro-osseous lesions of the jaws, with emphasis on their differential diagnoses. With a deeper understanding of benign fibro-osseous lesions, clinicians will be better prepared to manage these lesions in their practice.
