A huge adenomatoid odontogenic tumor of maxilla.

The adenomatoid odontogenic tumor (AOT) is a benign, nonneoplastic (hamartomatous) lesion with a slow progressing growth. It occurs in both intraosseous and peripheral forms. This paper reports the case of a female aged 16 years who presented with a swelling in anterior maxilla; canine was missing, and a supernumerary tooth was present in the mid line. Radiology revealed a well-defined radiolucent area associated with impacted canine and root resorption of adjacent teeth, which was diagnosed histopathologically as AOT. The patient was treated surgically and later rehabilitated with fixed prosthesis.
