The adenomatoid odontogenic tumor (AOT) is a rare benign odontogenic tumor that is mostly found in jawbone. It is generally found in the incisor region of the maxilla of young females. It rarely extends into the paranasal sinuses. This article describes a case of AOT found in the maxilla and occupying the maxillary sinus and nasal cavity.<br>A 20-year-old woman was referred to our department because of swelling of the left cheek. CT examination showed a cystic lesion in the left maxillary sinus including calcified structures and an impacted tooth. A biopsy specimen of the lesion revealed an adenomatoid odontogenic tumor. We performed tumor extirpation combined with the Caldwell-Luc operation. There is no evidence of recurrence 3 years after the operation.
