However, the rare peripheral variant occurs primarily in the gingival tissue of tooth-bearing areas [ 9 ]. Conservative surgical enucleation is the treatment modality of choice. Some sections were stained with haematoxylin-eosin. Recently, Crivelini et al. Radiographic features 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 ].

Adenomatoid odontogenic tumor AOT is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. Radiologically, he showed a 3 cm unicystic radiolucent image with a comparatively clear demarcation. The histological typing of the WHO defined the AOT as a tumor of odontogenic epithelium with duct-like structures and with varying degrees of inductive change in the connective tissue.

Many different names like adenoameloblastoma, ameloblastic adenomatoid tumor, adamantinoma, epithelioma adamantinum or teratomatous odontoma have been used before to define the lesion currently called AOT. 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 ].

Clinical features generally focus on complaints regarding a missing tooth. The tooth 43 was located on the floor of this process. Half a year after surgery a clinical and radiographic follow-up examination was performed.

Moreover, eosinophilic, uncalcified, adenomatoie material can be found and is called “tumor droplets”. The lesion usually present as asymptomatic swelling which is slowly growing and often associated with an unerupted tooth.

With respect to the age of the patient and the localization of the AOT in the lower jaw, the reported case is a rare example of this tumor entity. For radiological diagnose the intraoral periapical radiograph seems to be more useful than odonrogenic.
