case_images: Mandibular occlusal radiograph showed expansion of the cortical plates [Figure 1a] and a panoramic radiograph revealed a large unilocular radiolucency present in the body of mandible, extending from the root of right second premolar to the retromolar region. There was thinning but no discontinuity of the lower border of the mandible and displacement of the mandibular canal toward the lower border of mandible and radicular resorption of involved teeth [Figure 1b]. Axial computed tomographic examination was performed and revealed a well-circumscribed bony expansile cystic lesion measuring 6.1 x 2.5 x 4 cm in size, with the epicenter at ramus of mandible and extending into right half of body of mandible [Figure 1c].
case_images: (a) Intraoperative photograph after the curettage; (b) photomicrograph of the lesion showing numerous vascular spaces lined by endothelial cells and multinucleated giant cells (H and E, 10x); (c) photomicrograph showing multinucleated giant cells in the fibrous tissue (H and E, 40x)

case_images: The involved teeth were removed and curettage of the lesion was performed under general anesthesia [Figure 2a] and the tissue was sent for histopathologic evaluation. Hemosiderin pigment was seen at places along with giant cells, which was suggestive of ABC [Figure 2b and 2c.]
