The calcifying epithelial odontogenic tumor (CEOT) is a rare lesion of the jaws. It accounts for about 1% of all odontogenic tumors. The CEOT occurs primarily in the molar-premolar region of the mandible, and 52% of cases are associated with an unerupted tooth. This report describes an unusual case in a 37-year-old woman. The tumor arose in the molar area of the right mandible, appeared radiographically as a radiolucent lesion, and was thought to be a dentigerous cyst in association with an impacted first molar. The lesion was enucleated. Microscopic examination showed it to be a dental sac, within which were the 3 elements of a typical CEOT: squamoid cells with eosinophilic cytoplasm, the homogeneous eosinophilic substance, and calcium salt deposits in the form of Liesegang rings. |
