title: Bilateral Calcifying Cystic Odontogenic Tumour of Mandible: A Rare Case Report and Review of Literature.
abstract: Calcifying cystic odontogenic tumour (CCOT) is a relatively rare lesion of oral and maxillofacial region and forms only 2% of all odontogenic tumours. It was previously known as Calcifying odontogenic cyst and only recently has been classified as a tumour by WHO. The controversy regarding its origin can be owed to its diverse clinical and histopathological presentation and variation in reported malignant potential. It was first reported by Gorlin in 1962 and since then conundrum regarding its true nature has persisted. It is seen in association with other lesions like odontoma, ameloblastoma and ameloblastic fibroma. Both intra-osseous and extra-osseous forms of CCOT have been reported. It commnoly occurs in anterior region with equal preponderance in maxilla and mandible. Here we present a rare case of bilateral CCOT in the posterior mandible of a 16-year-old male patient which was discovered incidentally during a radiographic examination.
