Abstract
Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional information about AOT, all reports regarding AOT and cited in "pubmed" since 1990 onward were reviewed. AOT accounts for about 1% until 9% of all odontogenic tumors. It is predominantly found in young and female patients, located more often in the maxilla in most cases associated with an uneruppted permanent tooth. For radiological diagnose the intraoral periapical radiograph seems to be more useful than panoramic. However, AOT frequently resemble other odontogenic lesions such as dentigerous cysts or ameloblastoma. Immunohistochemically AOT is characterized by positive reactions with certain cytokeratins. Treatment is conservative and the prognosis is excellent. For illustration a rare case of an AOT in the mandible is presented.
Highlights
From the early 1990s onwards 65 single cases of Adenomatoid odontogenic tumor (AOT) have been published
Regarding the various case series published in the literature [e.g. [4,5,6,7,8]] and comparing these data with the single case reports mentioned above, it has to be
Comparing diagnostic arruracy between intraoral periapical and panoramic radiographs Dare et al [12] found that intraoral periapical radiographs allow perception of the radiopacities in AOT as discrete foci having a flocculent pattern within radiolucency even with minimal calcifies deposits while panoramic often do not
Summary
From the early 1990s onwards 65 single cases of AOT (excluding case series of more than 10 cases) have been published. [4,5,6,7,8]] and comparing these data with the single case reports mentioned above, it has to be (page number not for citation purposes) Unicystic radiolucent lesion in the lawer right jaw with a comparatively clear demarcation. Whereas the follicular variant shows a well-circumscribed unilocular radiolucency associated with the crown and often part of the root of an unerupted tooth, the radiolucency of the extrafollicular type is located between, above or superimposed upon the roots of erupted permanent teeth [3].
