Juvenile ossifying fibroma is a benign fibro-osseous lesion with aggressive biological potential that typically affects the craniofacial skeleton in children and adolescents. It is a large, asymptomatic tumor with aggressive behavior. Radiographically, it presents as a well-demarcated radiolucent or multitrabecular area that causes expansion and thinning of the tables. It has a recurrence rate ranging from 30% to 56%, associated with conservative treatment. The treatment of choice is surgical resection. We report the case of a juvenile ossifying fibroma in a 9-year-old male patient who presented with a 3-month history of asymptomatic swelling in the right upper jaw region, but with altered facial aesthetics. An incisional biopsy was performed, which revealed a juvenile ossifying fibroma. It was decided to perform a partial maxillectomy with preservation of the orbital floor with safety margins. Two weeks after the operation, no signs of recurrence were evident, and the patient's progress was favorable.
