Adenomatoid odontogenic tumor (AOT), a benign (hamartomatous) lesion of odontogenic origin, is an uncommon tumor which affects mainly. Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional. Adenomatoid odontogenic tumor is a hamartomous benign neoplasia of odontogenic origin. It appears mostly in young patients and females, the maxillary.

The interesting dysplastic dentin microscopic picture has led the World Health Organization WHO to classify the AOT in the odonrogenic of neoplasias and other tumors related to the odontogenic apparatus, benign subgroup composed by odontogenic epithelium with ectomesenchyme in the Histological Typing of Odontogenic Tumors Kramer, et al.
Adenomatoid odontogenic tumor, an uncommon tumor
AOT occurs mainly in the second decade of life, and is uncommon in patients older than 30 years of age. Views Read Edit View history. A surgical exposition of the crown odontogsnic bonding sdenomatoid a bracket on the maxillary left lateral incisor were also planned a coronoplasty of the first premolar to a canine shape. They would gradually decrease, however, due to compression of the tumoral mass as it grew. Few cases of AOT, like this case, were described in the literature in association with a maxillary lateral incisor.
The unilocular radiolucency is well demarcated with smooth cortical border.
In the AOT, PCNA revealed that the cells in the spindled areas and in the peripheral cords were the most proliferative, which could suggest that those sites would be responsible for the tumoral growth.
The recurrence rate is adenonatoid low as 0. This page was last edited on 26 Juneat It presents as a symptom-free lesion and is frequently discovered during routine radiographic examination. Br Dent J ; J Oral Pathol Med ; Primary antibodies were then incubated; their sources, adenomstoid, and times of incubation are listed in Table 1.
Study on the origin and nature of the adenomatoid odontogenic tumor by immunohistochemistry
International Histological classification of tumors. Aspiration of the smelling yielded 2 ml of straw color fluid mixed with blood.
Not rarely did these structures present a thin layer of the eosinophilic material in its internal surface. The maxilla is more commonly affected than the adenomxtoid.
Laminin was clearly expressed in the zone of the basal membrane, both of the epithelium and of the blood vessels, a pattern that was followed by collagen IV; however, with weaker expression, not rarely absent next to the epithelium. The extraction of the tooth 23 was done in Aprilwith surgery to bond a bracket on tooth 22, but it failed due to lack of the localization and the consistency of the tissues around the impacted tooth.
Some authorities feel that, given the slow growth and circumscription of the lesion, oodontogenic is best classified as a hamartoma rather than a true neoplasm [ 3 ].

How to cite this URL: Summary and Conclusion Even though enucleation and curettage for AOT is the most common treatment modality, accurate histological diagnosis is mandatory to avoid unnecessary mutilating surgery.

AOT affects young individuals with a female predominance, occurs mainly in the second decade, and usually surrounds the crown of unerupted odontogeniv. This material may stain for amyloid.
In Philipson and Birn proposed the name adenomatoid odontogenic tumor.

The epithelial cells may form rosette-like structures around a central space, which may be empty or contain a small amount of eosinophilic material. The consistency was bony hard and nonfluctuant. This stage is called “protective odontohenic of amelogenesis”, which avoids cementoblastic differentiation in the follicle and cementum deposition or “osteodentin” next to the enamel Ten Cate 23 Komal K, Vibhakar A.
As far as the extrafollicular variant, we agree with Philipsen, et al. Abstract Adenomatoid odontogenic tumor AOTa benign hamartomatous lesion of odontogenic origin, is an uncommon tumor which affects mainly females in the second decade. The swelling was slow growing; it gradually increased in size and led to the disfigurement odontogehic the face.
Females are affected about twice as often as males [ 3adenlmatoid8 ]. J Oral Maxillofac Pathol. Services on Demand Journal. Some authors prefer to disagree with the term AOT. Adenoameloblastoma; report of nine cases.
