adenoameloblastoma

adenoameloblastoma

 [ad″ĕ-no-ah-mel″o-blas-to´mah]
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.

Adenomatoid Odontogenic Tumour

An 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.

[1] Stafne, in year 1948 described it as an "ameloblastic adenomatoid tumor or adenoameloblastoma," since it presented with simulating structures such as canals or glands, he, therefore, described it as an ameloblastoma variant.
Later on it has been described under various names like adenoameloblastoma, cystic complex composite odontoma, ameloblastic odontogenic tumor, odontogenic adenomatoid tumor, and so forth.

En el pasado esta lesion fue descrita como una variedad del ameloblastoma, siendo denominada adenoameloblastoma, posteriormente se reconoce como una entidad patologica diferente de acuerdo a su naturaleza, comportamiento e histologia(5)(30)(3).
Adenomatoid odontogenic tumor (AOT) is a rela-tively uncommon distinct odontogenic neoplasm that was first described by Steensland in 1905.1 This tumor was initially labeled as 'epithelial tumor' by Stafne in 1948 and as adenoameloblastoma by Thoma in 1955.
As a result, the lesion is known by many names, including adenoameloblastoma, adenoameloblastic odontoma, epithelial tumour associated with developmental cysts, ameloblastic adenomatoid tumour and adenomatoid or pseudoadenomatous ameloblastoma.
