Calcifying odontogenic cyst

Calcifying odontogenic cyst (COC) is a form of odontogenic cyst. There is some disagreement on the terminology and classification of this lesion.

It may represent around 0.3-0.8% of all odontogenic cysts 2.

It can show extreme diversity in its clinical and histopathological features, as well as in its biological behavior. 

A notable histopathological feature includes a cystic lining demonstrating characteristic "Ghost" epithelial cells with a propensity to calcify. 

Treatment options include enucleation and curettage. 

It was described by Gorlin in 1962 4.
