Adenomatoid Odontogenic Tumour of Mandibular Anterior Region: Review of Literature and Report of a Rare Case

Adenomatoid odontogenic tumour (AOT) is a rare, benign odontogenic tumour, which is often misdiagnosed as an odontogenic cystic lesion. It accounts for about 3% of all the odontogenic tumours. It is predominantly located in the anterior maxilla in the young female patients and in most cases is associated with an un-erupted permanent tooth. It is a hamartomatous, non-invasive lesion with slow but progressive growth. There are three clinicopathologic variants of AOT: intra-osseous follicular, intra-osseous extra-follicular and peripheral type. A rare case of intra-osseous extra-follicular type of AOT in the mandibular anterior region (unusual site of AOT) in a 16-year-old female patient is reported with its detailed clinical and radiographical features.
