Adenomatoid Odontogenic Tumour with Calcifying Epithelial Odontogenic Tumour Component: A Rare Report of an Intricate Histomorphology

Keshava K Bhat, Reshma Amin, Pushparaja Shetty


The Adenomatoid odontogenic tumour (AOT) is a benign, gradually developing, non-invasive tumour. It is recognised by its exceptionally notable duct like structures. The present case of adenomatoid odontogenic tumour with calcifying epithelial odontogenic tumour (CEOT) component revealed areas of AOT in the majority of the fields. Further detailed microscopic examination unveiled few CEOT like areas displaying excessive calcifications, giving rise to histological features of two odontogenic tumours in unison. This brings out with one of the unusual histopathologic combinations reported in the literatures with a brief review of the literature.
