Fig. 2 (a) Axial CT shows an osteolytic lesion with the destruction of buccal cortex in the right mandible. (b) The buccal cortex shows a moth-eaten appearance on a coronal reformatted CT. (c) Sagittal reformatted CT shows the lesion affecting the mandibular canal. (d) Three-dimensional reconstructed CT shows the lesion affecting the mental foramen.

Fig. 4 Microscopic findings. (a) Histopathological findings of the surgical specimen of the ascending colon (primary site). Moderately differentiated adenocarcinoma was observed. Glands were irregular and tortuous. The nuclei were elongated and stratified. (b) Histopathological findings of the biopsy specimen of the right mandible (metastatic site). Adenocarcinoma similar to the primary tumor and mandibular bone spicules (*) were observed. Bars: 100μm.
