Adenomatoid odontogenic tumour: An enigma

Adenomatoid odontogenic tumour (AOT) is an uncommon, hamartomatous, benign epitheial lesion of odontogenic origin. The current World Health Organisation (WHO) classification of odontogenic tumors defines AOT as being composed of the odontogenic epithelium in a variety of histoarchitectural patterns, embedded in mature connective tissue stroma, and characterized by slow, but progressive growth. The aim of this paper is to present three rare cases of intraosseous AOTs with varied clinical and radiographic features imposing the fact that AOT should be included in differential diagnosis of routine odontogenic cysts and tumours.
