ABSTRACT Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, constituting only 3% of all odontogenic tumors. AOT is characterized histologically by the formation of duct-like structures with amyloid-like deposits. An 18-year-old male presented with right chek swelling. CT scan revealed well-defined expansile heterogeneous mass with central hypodensity. Patient underwent excision of the mass by Caldwell-luc approach and histopathologically the diagnosis adenomatoid odontogenic tumor was made. Since it is a benign tumor, the treatment should consist of enucleation and curettage.
