CALCIFYING CYSTIC ODONTOGENIC TUMOR- A RARE CASE REPORT

Abstract

Calcifying cystic odontogenic tumours (CCOTs) account for around 2% of all odontogenic tumours. The term "Calcifying Ghost Cell Odontogenic Cyst" (CGCOC) is also commonly used to describe this condition. It was first recognized as a distinct entity by Gorlin et al. in 1962. It has its roots in the odontogenic stage of development. This unusual lesion can resemble either a solid tumour or a cyst. Although extra-osseous or peripheral forms of the disease are possible, intra-osseous lesions are much more common [1]. There have been several changes in the terminologies used to describe this condition and various classifications have been made by several authors since its first description. In 2005, the World Health Organization(WHO) reclassified the growth as a calcifying cystic odontogenic tumour (CCOT). This report describes a case of CCOT with an impacted mandibular 3rd molar.
