Resumo: WHO-type Juvenile ossifying fibroma (wJOF) is an uncommon aggressive benign neoplasm that can be confused with osteosarcomas. In the present case, a 19-year-old male patient presented with an asymptomatic tumor in the anterior region of the mandible, causing tooth displacement, with an evolution of five months. Imaginologic exams revealed a mixed lesion with imprecise limits, extending from tooth 35 to 45, causing expansion and rupture of the cortical bones. Incisional biopsy showed intense fasciculated spindle cell proliferation, deposition of cellular osteoid trabeculae, and focal collections of multinucleated giant cells. The final diagnosis was wJOF. Segmental mandibulectomy and reconstruction with a fibular flap were performed. No recurrence was observed after 14 months. To contribute to better knowledge and proper clinical management of these entities, a discussion on the criteria of differential diagnosis of wJOF with benign and malignant intraosseous lesions of the jaws, including the psammomatoid variant, is herein provided.
