During the last few years several studies have been published dealing with the immunhistological properties of AOT. One year ago the dentist diagnosed a cyst with a ectopic lower right canine tooth by an x-ray.

Histologically, the tumor is solid and there is a cyst formation Fig. J Clin Pediatr Dent. All authors disclaim any financial or non-financial interests or commercial associations that might pose adenomatois create a conflict of interest with information presented in this manuscript.

For illustration a rare case of an AOT in the mandible is presented. The tumor may be aenomatoid cystic, and in some cases the solid lesion may be present only as masses in the wall of a large cyst [ 14 ]. 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 ].
