Adenomatoid Odontogenik Tumor (AOT): A Case Report

Adenomatoid odontogenic tumor (AOT) is a relatively uncommon neoplasm originating from
odontogenic epithelium, accounting for approximately 3–7% of all odontogenic tumors. It is a
benign, non-invasive lesion characterized by slow but progressive growth. AOT is more commonly
found in the maxilla, particularly in females, and is frequently associated with impacted canines.
We report a case of A 14-year-old female presented with a swelling on the left side of her upper
jaw, which had been gradually enlarging over the past year. The lesion increased in size over time.
Extraoral examination showed facial asymmetry. A solitary, diffuse, hard mass on the left anterior
maxilla. The overlying mucosa appeared normal, and the lesion measured approximately 2.5 cm in
diameter while tooth 22, 23, and 24 were unerupted.
The lesion was treated by enucleation, along with removal of the embedded teeth.
Histopathological examination confirmed the diagnosis of adenomatoid odontogenic tumor. No
recurrence was observed during a 6-month follow-up period.
