  Fig. 1 A. Front view of the patient showing an erythematous, protruding mass on the left side of the face. B. Left lateral view showing significant swelling in the left preauricular region, measuring 3×4 cm. C. The histopathologic findings reveal solar elastosis in the upper dermis and necrotic fat tissue with fibrosis in the subcutaneous fat layer (H&E staining, ×40). D. Chronic inflammation with fibrosis was also observed in the muscle layers (H&E staining, ×40).

  Fig. 2 A, B. Magnetic resonance imaging shows extensive inflammation in the infratemporal fossa and in the adjacent soft tissues. C. The dashed arrow indicates inflammation of the masseter muscle, and the long arrows indicate the pterygoid muscle. Abscess formation with peripheral rim enhancement is observed in the adjacent soft tissues, which is indicated by the short arrows. Osteomyelitis is observed at the ramus (short arrows; D) and the body of the left mandible (short arrows; E). F. Inflammation originating from dental infection is also observed with peripheral enhancement (short arrows). G. Evaluation was performed with digital panoramic radiography. There were no canine, premolars, or molars in the left mandible. A diffuse area of haziness in the left mandible was observed.
