Adenomatoid odontogenic tumor in the maxillary antrum: A rare case entity

Abstract

Adenomatoid odontogenic tumor (AOT) is an uncommon benign tumor of odontogenic origin. It occurs in the second decade of life. Females are more commonly affected than males. AOT has a striking tendency to occur in the anterior maxilla; however, very few cases have been reported to occur in the maxillary antrum. This is a case report of a 17-year-old male presented with a large radiolucent lesion associated with the crown of an unerupted canine located in the right maxillary antrum, which was clinically diagnosed as dentigerous cyst. The histopathological examination revealed the presence of AOT.
