case_images: Extraoral examination revealed an ill-defined, diffuse, and bony hard swelling of approximately measuring about 6 cm x 4 cm on the left side of the face, extending superior-inferiorly from left zygomatic arch till angle of the mandible and anteroposteriorly from nasolabial fold till tragus of the left ear with normal overlying skin [Figure 1a and b] Intraorally, swelling was solitary, slightly tender with the expansion of buccal and lingual cortical plates with no pathological changes to the overlying mucosa.
