Adenomatoid Odontogenic Tumour (AOT) constitutes about 5% of all odontogenic tumours and is most commonly seen in young females, in association with impacted maxillary canines in a Dentigerous Cyst (DC) like relationship. Extrafollicular AOT is an uncommon variant seen unassociated with impacted teeth. Rare cystic presentation is reported with most cases seen arising from or in association with DC. Here, the authors present a case of extrafollicular AOT in a 29-year-old Dravidian male, who reported with a chief complaint of swelling of lower anterior jaw region. Radiographically, a well-defined radiolucent lesion was noted extending from mesial aspect of the roots of right mandibular second molar, crossing the midline to involve the body of mandible till mesial aspect of lower left canine. There was evidence of cortical perforation. The lesion was excised and sent for histopathological evaluation. Histopathologically, the lesion was diagnosed as cystic AOT-extrafollicular variant. There was adequate healing and no signs of recurrence or residual disease were noted 18 months after the surgery. The present case is a unique presentation of cystic extrafollicular AOT with pictorial demonstration and detailed explanation of its pathogenesis.
