The adenomatoid odontogenic tumor is an odontogenic tumor[cite journal |author=Nigam S, Gupta SK, Chaturvedi KU |title=Adenomatoid odontogenic tumor - a rare cause of jaw swelling |journal=Braz Dent J |volume=16 |issue=3 |pages=251–3 |year=2005 |pmid=16429194 |doi=/S0103-64402005000300015 |url=http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-64402005000300015&lng=en&nrm=iso&tlng=en] arising from the enamel organ or dental lamina. ]It is more common in young people and affects females more than males.
Presentation and diagnosis
The most common location is in the anterior maxilla.[cite journal |author=Nonaka CF, de Souza LB, Quinderé LB |title=Adenomatoid odontogenic tumour associated with dentigerous cyst--unusual case report |journal=Rev Bras Otorrinolaringol (Engl Ed) |volume=73 |issue=1 |pages=129–31 |year=2007 |pmid=17505612 |doi= |url=http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0034-72992007000100022&lng=en&nrm=iso&tlng=en] ]In 75% of cases, it is associated with an unerupted tooth.
On radiographs, the adenomatoid odontogenic tumor presents as a radiolucency (dark area) around an unerupted tooth extending past the cementoenamel junction.
It should be differentially diagnosed from a dentigerous cyst and the main difference is that the radiolucency in case of AOT extends apically beyond the cementoenamel junction.
Radiographs will exhibit faint flecks of radiopacities surrounded by a radiolucent zone.
It is sometimes misdiagnosed as a cyst.[cite journal |author=Handschel JG, Depprich RA, Zimmermann AC, Braunstein S, Kübler NR |title=Adenomatoid odontogenic tumor of the mandible: review of the literature and report of a rare case |journal=Head Face Med |volume=1 |issue= |pages=3 |year=2005 |month=August |pmid=16270916 |pmc=1266042 |doi=10.1186/1746-160X-1-3 |url=http://www.head-face-med.com/content/1//3] ]References
