Peripheral calcifying odontogenic cyst.
BACKGROUND
Calcifying odontogenic cyst (COC) is a rare lesion representing about 1% of jaw cysts. It may occur in a central (intraosseous) or peripheral (extraosseous) location.


METHODS
A case of peripheral COC located on the gingiva, appearing as a painless, circumscribed, pink nodule has been reported.


RESULTS
Peripheral, in contrast to central, COC tends to affect older patients. Peripheral COC is a less aggressive lesion than the central counterpart, and a simple excision biopsy is curative.


CONCLUSIONS
The histological finding of a keratinized epithelium rich in ghost cells has helped in making the diagnosis.
