Juvenile trabeculated Ossifying Fibroma (JTrOF) is commonly arising from the maxilla and the mandibular bones, while Psammomatoid Juvenile Ossifying Fibroma (PsJOF) commonly arises in the sinonasal and calvarial bones. In our paper, we described a 12-year-old pediatric female who presented with a right fronto-orbital disfiguring swelling. She underwent total resection, peripheral osteotomy, and reconstruction. Pathology reported a TrJOF associated with Aneurysmal Bone Cyst (ABC) formation. TrJOF rarely originates from superolateral wall orbital bone, and it is exceedingly rare when it is associated with ABC formation. Pathologically, it is difficult to distinguish TrJOF from other FOLs due to similarities and overlap. The ideal treatment is total surgical excision and reconstruction. The Surgical resection is challenging as regards functional and cosmetic outcomes.
