an odontogenic tumor with formation of ductlike structures in place of or in addition to a typical ameloblastic pattern.
ad·e·no·ma·toid o·don·to·gen·ic tu·mor
a benign epithelial odontogenic tumor appearing radiographically as a well-circumscribed, radiolucent-radiopaque lesion usually surrounding the crown of an impacted tooth in an adolescent or young adult; characterized histologically by columnar cells organized in a ductlike configuration interspersed with spindle-shaped cells and an amyloidlike deposition that gradually undergoes dystrophic calcification.

[ad′ənō·amel′ōblastō′mə] pl. adenoameloblastomas, adenoameloblastomata
a benign tumor of the maxilla or mandible composed of ducts lined with columnar or cuboidal epithelial cells. It develops in tissue that normally gives rise to the teeth, and it most often occurs in young people.
Adenomatoid Odontogenic TumourAn uncommon and usually asymptomatic, non-invasive hamartomatous lesion with slow progressive growth which accounts for 2–13% of all odontogenic tumours. AOT usually affects young patients, under age 30, has a male:female ratio 1:2, and occurs in the anterior maxillary region. It is thought to arise from the odontogenic epithelium of the dental laminar complex or its remnants. It is often associated with impacted canines.
Imaging Cystic radiologic appearance.
Management Curettage teeth.
