Juvenile trabecular ossifying fibroma: case report

Abstract

Trabecular juvenile ossifying fibroma (TrJOF) is a rare benign fibro-osseous lesion, with aggressive behavior, high recurrence potential, which affects the craniofacial skeleton of children and adolescents. This paper aims to describe a clinical case in a female patient, 8 years old, who attended the Oral and Maxillofacial Pathology outpatient clinic - Faculty of Dentistry - University of Gurupi - UNIRG, city of Gurupi - Tocantins - Brazil for clinical evaluation of an increased in volume in the region of the mandible body, on the left side. There was no painful symptomatology or even discomfort. Imaging examinations (panoramic radiography and computed tomography (CT) showed an extensive radiolucent area that extended from the first permanent molar with incomplete root formation to the central incisor on the opposite side. After performing an incisional biopsy and histopathological examination, the lesion was completely removed included the remainder deciduous teeth overlying the tumor. In the postoperative control images at 90 days (panoramic radiography and CT), signs of bone neoformation with basilar thickening and the germs of the permanent teeth in full development were noted. In view, this importance of knowledge of clinical, radiographic and histopathological aspects is emphasized for the realization of a correct diagnosis and adequate treatment in order to reduce the high rates of relapses.
