Abstract
The calcifying odontogenic cyst (COC) was first described as a distinct entity by Gorlin in 1962.The lesion is a mixed odontogenic benign tumor, and although most of the cases present cystic characteristics, a few are of the solid type and its rare malignant transformation is well documented. The COC may occur in association with other odontogenic tumors, the most common is odontoma, and occurring in about 24% of the cases for this association the term Odontocalcifying odontogenic cyst has been suggested. Radiographically is a well-defined mixed lesion and histological consists of a large cyst and ghost cells have been regarded as pathgnomonic for calcifying odontogenic cyst. A large controversy regarding COC terminology and classification exists, in the latest WHO publication on odontogenic tumors it was classified as a benign odontogenic tumor and was renamed as calcifying cystic odontogenic tumor (CCOT). It seems that the COC has two features of cyst and neoplasm. In spite of several dualistic classifications of COC, confusion about terminology and nature still exists. COC and the odontoma may represent coincidental juxtaposition of COC or odontogenic tumor develops in the wall of the preexisting COC. This review is of a calcifying odontogenic cyst associated with odontoma and its proposed terminology Odontocalcifying Odontogenic cyst (COCaO) a brief pathogenesis is discussed.
