Epidemiology From the early s onwards 65 single cases of AOT excluding case series of more than 10 cases have been published. However, AOT frequently resemble other odontogenic lesions such as dentigerous cysts or ameloblastoma. Odontogenic tumors in Mexico: Abstract Adenomatoid odontogenic tumor AOT is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. Calcification is sometimes seen and may be extensive Fig.
The lesion usually present as asymptomatic swelling which is slowly growing and often associated with an unerupted tooth. The tumor is most often diagnosed in the tumoor decade of life and women are about adenomatois as adenomatoi affected than men. No root resorption could be observed. AOT should be considered in the differential diagnosis of radiolucent jaws swelling, although its low incidence.
There was no evidence of recurrence and adenomatid apical resorption of the adjacent teeth could be observed Fig. The postoperative course was uneventful. Limitation of panoramic radiography in diagnosing adenomatoid odontogenic tumors. The radiographic findings of AOT frequently resemble other odontogenic lesions such as dentigerous cysts, calcifying odontogenic cysts, calcifying odontogenic tumors, globule-maxillary cysts, ameloblastomas, odontogenic keratocysts and periapical disease [ 10 ].
Both patients have been treated under general anesthesia for the removal of the lesions with unerupted tooth. The tooth 43 was located on the floor of this process.
However, all of these reported lesions did not show macroscopically visible pigmentation. Displacement of neighbouring odontoyenic due to tumor expansion is much more common than root resorptions. No resorption of the root apices was observed Fig. Some sections were stained with haematoxylin-eosin.
SB and AZ carried out the pathohistological investigations and participated in creating this part of the manuscript.

For periodontal intrabony defects caused by AOT guided tissue regeneration with aadenomatoid technique is suggested after complete removal of the tumor [ 23 ]. Cite this article as. Journal List Head Face Med v.
The postoperative course and follow-up were uneventful. During the last few years several studies have been published dealing with the immunhistological properties of AOT.

Repair of an intrabony defect from an adenomatoid odontogenic tumor. The tumor may be partly cystic, and in some cases the solid lesion may be present teview as masses in the wall of a large cyst [ 14 ].
Moreover, eosinophilic, uncalcified, amorphous material can be found and is called “tumor droplets”. Panoramic radiograph before therapy. National Center for Biotechnology InformationU.

Adenomatoid odontogenic tumor of the mandible: review of the literature and report of a rare case
Adenomatoid odontogenic tumor AOT is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. Half a year after surgery a clinical and radiographic follow-up examination was performed. In addition, in one recently reported case MRI was useful to distinguish AOT from other lesions, even if it is difficult on periapical ordinal radiographies [ 10 ].
