Calcifying Odontogenic cyst (COC) or Gorlin cyst is an uncommon benign cystic lesion which develops from the odontogenic epithelium. According to WHO it is classified under developmental Odontogenic cysts. They occupy a spectrum ranging from a cyst to an odontogenic tumor. It most commonly involves the anterior region of the jaws. The characteristic feature of COC is the presence of Ghost cells within the epithelium that has a propensity to calcify. In this paper we illustrate a case of COC in a 14-year-old girl, and the investigations done to arrive at the final diagnosis.
