Figure legends
Figure 1. Intraoral view. (A, B) Intraoral view revealed a well-defined, painless, elastic hard mass, measuring 17×17 mm in size between the right mandibular canine and first premolar.
Figure 2. Panoramic X-ray. Panoramic radiography showed a radiolucent area in the alveolar bone between the right mandibular canine and first premolar.
Figure 3. Computed tomography findings . (A, B ) Compressive bone resorption of the alveolar bone between the right canine and first premolar of the mandible.
Figure 4. Magnetic resonance imaging findings. Endophytic appearance of a well-defined enhancing mass on the right side of the mandible on T2-weighted images.
Figure 5. Histopathological findings. (A ) Scattered cord-like and lump-like epithelial components were observed in the fibrous tissue near the base of the tumor (H-E staining, ×40).
(B ) Cementum- or bone-like calcifications were observed. Epithelial components resembled Marasse’s remaining epithelial or Hertwig epithelial sheath and were positive CK19 (H-E staining, ×400; CK19 staining, ×40).
