The calcifying epithelial odontogenic tumor is a benign epithelial odontogenic lesion that accounts for less than 1% of all odontogenic tumors. It is most frequently seen in the posterior areas of the mandible. Extension of this lesion to the maxillary sinus is extremely rare. In this paper, we report the fourth of such cases which has been reported, up to now. This tumor was encased between the right maxillary lateral and canine roots with extension to the maxillary sinus. Histologically, the tumor is composed of sheets of epithelial cells with eosinophilic or clear cytoplasm, intercellular bridges, nuclear pleomorphism, but no mitotic figures, amorphous eosinophilic and calcified materials were seen within the sheets of epithelial cells.
