Abstract: The fourth edition of the World Health Organization classification of head and neck tumours summarizes changes in odontogenic and maxillofacial tumours and reintroduces a chapter on odontogenic cysts that reclassifies calcifying odontogenic cystic tumours as calcifying odontogenic cysts based on lack of evidence to substantiate them as true neoplasms. This article presents an unusual case report of a calcifying odontogenic cyst treated successfully with enucleation in support of the view of recent classification.

Clinical relevance: Calcifying odontogenic cysts are rare entities that can be managed successfully by enucleation, supporting the WHO position that these cysts are not neoplasms.
