Resumo: The purpose of this study was to report a rare case of bilateral mandibular trabecular juvenile ossifying fibroma (TJOF) in a pediatric patient. A 13-year-old male patient presented to the dentist with swelling of the right face. Cone beam computed tomography revealed hypodense areas associated with hyperdense islands and expansion of the cortical bone in the bilateral posterior mandibles. An incisional biopsy was performed. Histologic analysis revealed irregular trabeculae of immature bone and calcified bone structures in a hypercellular stroma with spindle cells. The cells were immunopositive for SATB2 marker and negative for AE1/AE3 cytokeratins. The final diagnosis was TJOF. Enucleation, curettage, and peripheral osteotomy using a rapid prototyping biomodel of the tumors were performed. At the 12-month follow-up, a left-sided recurrence was noted, and another surgical approach was performed. Postoperative tomographic images suggested appropriate healing at the 24-month follow-up, demonstrating complete removal of the tumor.
