Figure 1 Physical examination images. A and B: The patient’s clinical presentation with a firm swelling on her left gum below the first pre-molar tooth and minimal swelling on the left lower jaw; C: A panoramic radiographic image revealed a singular, well-demarcated, circular lesion in the left mandible body.

Figure 2 Computed tomography scan with 3D reconstruction revealed a circular-shaped lesion in the left mandible body with a well-defined radiolucent border, sized 2. 3 cm × 2.8 cm × 0.9 cm.

Figure 3 Lip-split incision approach was used and continued with marginal mandibulectomy. Drain insertion was performed, and wound closure was carried out with a subplatysmal flap.

Figure 4 Pathology examination images of the excised tumor. A and B: Tumor specimen under the microscope at × 10 magnification; C: Tumor specimen under the microscope at × 40 magnification. It showed the bone trabecular component and fibrous connective tissues with spindle-shaped cells with cigar-shaped nuclei, eosinophilic cytoplasm, and smooth chromatin.
