Abstract

The calcifying epithelial odontogenic tumor (CEOT), also known as the Pindborg tumor, is a benign and rare odontogenic tumor accounting for 0.4-3 percent of all odontogenic tumors. Few reports of the incidence of this tumor exist in Iran. The most frequent location is the mandibular pr­emolar and molar area; less frequently the lesion is found in the maxilla. In clinical features, a painless slow-growing swelling will be seen. Micr­oscopically large sheets of epithelial cells in few fibrous stroma, large areas of amorphous, eosinophilic hyalinized (amyloid-like) material and calcification in concentric rings formation within the amyloid-like mate­rial will be detected. The authors report a peculiar case of Pindborg tum­or characterized by a rare localization of the lesion extending from anter­ior to the posterior of the upper jaw and by the young age of the patient.
