case_images: Image of the oral mass obtained intraoperatively. The patient is in dorsal recumbency, and the oral mass is located distal to the left mandibular deciduous third premolar tooth.

case_images: On presentation, a conscious oral examination revealed an ulcerated, broad-based soft tissue mass located distal to the left deciduous mandibular third premolar tooth (Figure 1).
case_images: Representative multiplanar views of the surgical planning CT. (A-C) Transverse, sagittal and dorsal bone window views of the left caudal mandible. No evidence of lysis or periosteal reaction. (D-F) Transverse, sagittal and dorsal post-contrast enhancement soft tissue window views of soft tissue mass (indicated by the blue arrow). Adjacent to the developing left mandibular permanent first molar, a 2.5 x 1.6 x 1.1 cm, soft tissue attenuating, minimally contrast enhancing mass was noted. The mass extended rostrally to the level of the left mandibular deciduous third premolar and caudally along the medial margin of the left mandibular body.

case_images: Whole-body computed tomography (CT) was performed with and without contrast administration for surgical planning as well as tumor staging (Figure 2).
case_images: Representative views of computer-generated 3-D render of CT performed immediately post-operatively (A) and 8 weeks following surgery (B) and multiplanar views of newly formed mandible, dorsal view (C) and sagittal view (D). New mandibular bone is noted to span the region from the osteotomy site to the mandibular symphysis. The appearance of the newly formed bone has internal trabecular markings that are sclerotic in appearance and a thin cortex present at the periphery. No overt mandibular canal is present.

case_images: The same anesthetic protocol was utilized, and CT scan of the head was performed, revealing new mandibular bone formation from the ostectomy site to the level of the mandibular symphysis (Figure 3).
