Abstract

The calcifying cystic odontogenic tumor (CCOT) simultaneously occurring with other lesions at different locations in the same patient is rare. We report a patient with CCOT associated with an odontoma, a supernumerary tooth, and a dentigerous cyst simultaneously occurring in the maxilla. Cone-beam computed tomography (CBCT) images showed a well-defined expansile lesion with internal calcification, high-density masses surrounded by low-density area, and a supernumerary tooth at the anterior maxilla. Posterolaterally to these lesions, an embedded canine with pericoronal radiolucency was detected. Histopathologic examination revealed a CCOT associated with an odontoma, a supernumerary tooth, and a dentigerous cyst of the embedded canine. Enucleation was performed, and a 2-year postoperative follow-up was uneventful. CBCT was useful in giving the differential diagnosis by depicting internal calcification of CCOT, and in revealing the extent and complex relationship of these lesions.
