Adenomatoid odontogenic tumour a relatively rare neoplasm constitutes about 2-7% of odontogenic cysts and tumours combined. Also known as the tumour of the 2/3rd due to its clinical and radiographic features. The recent research focussed on histiogenesis suggested towards an origin towards content of the gubernaculum cord and its remenants. With the characteristic histopathological features the diagnosis is a very straight one with all the three variants showing prognostically no significant difference. Recent advances have enlightened the understanding of molecular mechanisms involved with the various aspects of this enigmatic entity.
