case_images: On clinical examination, there was an extra-oral swelling over the right side of the midface, involving infraorbital rim, zygoma, zygomatic arch, maxilla and lateral side of the nose around 6 cm x 5 cm, which was hard in consistency causing significant facial asymmetry [Figure 1].

case_images: FD, osteoid osteoma and low-grade intermedullary osteosarcoma. Further radiological investigations included orthopantomogram which revealed a 'ground-glass appearance' and cone-beam computed tomography (CBCT) of skull involvement of right side maxilla, zygoma, nasal bone, sphenoid bone and pterygoid plates [Figure 3].
