An adenomatoid odontogenic tumour (AOT) or “adeno-ameloblastoma” is a slow growing benign, non-invasive, non-aggressive neoplasm of odontogenic origin. It is also referred to as a two-third tumour, as it is most prevalent in females and in the maxilla and impacted canine in two third of the cases clinically. Radiographically it is present with peri-coronal radiolucency with or without radio-opaque foci within the radiolucency. The most common variant is the follicular type (71%), often mistaken as a dentigerous cyst and the peripheral type being the rarest (18%).
Here, we present a case of AOT in the left maxillary region in a 13 year-old female, painless with facial asymmetry as swelling, along with an impacted left upper canine, lateral incisor and unilocular radiolucency with multiple radiopaque flecks radiographically. The pushing away of the canine near to the floor of the orbit and lateral incisor to the mesial wall of the antrum makes this case unique.
