case_images: Intraoral mass (A), intraoral radiographs (B,C), and cone-beam computed tomography reconstructed panoramic view (D) in a dog with ghost cell odontogenic carcinoma. Description of the intraoral mass extending from the gingival mucosa to mandibular skin (A). Radiographic findings include horizontal bone loss at the mesial aspect of the mesial root of the right mandibular fourth premolar (arrow) and increased radiolucency extending from the right mandibular fourth premolar to the mesial aspect of the first molar (open arrows) (B). The right rostral mandible shows poorly demarcated osteolytic radiolucency with dorsally displaced first and second premolars (C). In the panoramic view, radiolucency is observed in the interradicular bone of the right mandibular first molar (open arrow) compared to that of the left mandible (D).

case_images: Occlusal traumatic ulcers were evident on the dorsal aspect of the mass, originating from the ipsilateral maxillary canine and premolar (Figure 1A). Intraoral radiography revealed osteolysis extending from the right mandibular canine to the fourth premolar, horizontal bone loss (Figure 1B), and dorsal displacement of the right mandibular first and second premolars (Figure 1C). Skull CBCT revealed radiolucency in the interradicular bone of the right mandibular first molar (Figure 1D).
case_images: Cone-beam computed tomography showing transverse (A-C) and dorsal (D) images and sagittal (E) and dorsal (F) views of the 3D volume reconstructed rendering created from the CBCT images of a dog with ghost cell odontogenic carcinoma. Destructive bone lesion (open arrow) in the apical area of the right mandibular canine, along with a large tumor (A). Calcifications (arrows) are visible on the buccal aspect of the right mandible (B). The mass has invaded the interradicular bone of the right mandibular first molar. The invasive lesion is in close proximity to the mandibular canal (arrow) (C). A destructive bone lesion (curly bracket) is observed from the right mandibular canine to the interradicular bone of the first molar (D). Osteolysis observed between the right mandibular canine and fourth premolar regions, with dorsally displaced first and second premolars (E). Bone loss (arrow) extends to the lingual aspect of the mesial root of the right mandibular first molar tooth (F).

case_images: A destructive bone lesion involving the apical area of the right mandibular canine, along with a large tumor, was evident (Figure 2A). Calcified lesions were observed around the buccal aspect of the right mandibular fourth premolar and first molar (Figure 2B). The mass had invaded the interradicular bone near the mandibular canal of the right mandibular first molar (Figure 2C), and a destructive bone lesion extended from the right mandibular canine to the interradicular bone of the first molar (Figure 2D). Three-dimensional volume reconstructions created from CBCT images demonstrated osteolysis between the regions of the right mandibular canine and fourth premolar (Figure 2E), as well as bone loss extending to the lingual aspect of the mesial root of the right mandibular first molar (Figure 2F).
