The Adenomatoid Odontogenic Tumor (AOT) is a benign, non-neoplastic lesion with a slow but progressive growth. Because of the slow and confined growth of the lesion, it has been classified as a hamartoma rather than a true neoplasm. It occurs in both intraosseous and peripheral forms. The intrabony variant comprises of a follicular and an extrafollicular type. Radiographically the follicular type is associated with an impacted tooth and constitutes about 73% of the lesions, and the extrafollicular type is not associated with an unerupted tooth and accounts for about 24% of the tumors appearing as a unilocular radiolucency. Here we report the case of a large extrafollicular AOT involving the right parasymphysis and body of mandible in a 35 year old female patient.
