Juvenile Ossifying Fibroma: Case Report

Abstract

Type of work: Case report

Knowledge area: Maxillofacial surgery, pediatric dentistry

OBJECTIVES: To present the management of a juvenile ossifying fibroma and its follow-up.

INTRODUCTION: Juvenile ossifying fibroma is a benign fibro-osseous lesion with local aggressive growth, affecting the adjacent anatomical structures and with slow growth. This lesion has a predominantly soft tissue consistency with variable amounts of calcification. It is a large, asymptomatic tumor and the term juvenile is used because it affects people under 15 years of age. A recurrence rate between 30% and 58% is reported. METHODS :A fourteen-year-old female patient attends the Children's Dentistry Graduate School of Dentistry, referred from the University Hospital of Torreón, to assess an increased mass in the left maxilla, with an evolution of 4 months. In the clinical examination, a swelling in the maxilla is observed, with displacement of the premolars, affecting the occlusal plane, asymptomatic, without sensory compromise. An incisional biopsy is performed and referred to pathology. After clinical, imaging and histological analysis, juvenile ossifying fibroma was diagnosed. RESULTS: The treatment was enucleation of the tumor. In the surgical procedure, a total removal of the mass and a bone curettage were performed, mobility in the organs involved was observed. The affected area is splinted. Clinical and radiographic controls are carried out until resolution of dental mobility. CONCLUSIONS: Ossifying fibroma is a benign neoplasm with local aggressive behavior; it is important to make a timely diagnosis and avoid extensive surgical treatments. Long-term imaging control is important to avoid recurrences.
