Odontoma-associated calcifying cystic odontogenic tumour: Report of a case

The calcifying cystic odontogenic tumour (CCOT) is an uncommon benign neoplasm of odontogenic origin, which was first described by Gorlin. It has been shown to have extensive diversity in its clinical and histopathological features and its biological behaviour. Most of these cases present with cystic characteristics, but a few are of the solid type. Cystic variant of CCOT associated with odontoma is considered as rare variant. A case of calcifying cystic odontogenic tumour associated with odontoma is reported in an 11-year-old female patient. In this report, the lesion was very large extending from the midline up to the right tuberosity region and impeded the eruption of five permanent teeth. Through this article, the radiographic and histopathological features of this entity are discussed and the literature is reviewed.
