“…A multitude of authors during the early 1900s has been given credit to researchers like Steensland, Dreybladt, and James and Forbes for reporting the first case of AOT 6. AOT are less frequent than odontoma, cementoma, myxoma and ameloblastoma 7. It has been suggested by some authorities that this tumour may be a hamartoma rather than a true neoplasm, due to the limited size and to the lack of recurrence of most cases 8.…”

Adenomatoid odontogenic tumour (AOT) is an uncommon, benign tumour that represents 3-7% of all odontogenic tumours. It is slow growing, occurs twice as common in females and usually in the second decade of life. There are three subclinical types of this tumour with identical histology: follicular type (73%), extrafollicular variant (24%) and peripheral form (3%). Here, the authors have presented two rare cases of extrafollicular varieties of AOT in 25-year-old female patients, of which one was situated in the maxillary canine area and the other one situated in an unusual location of mandibular premolar area. Such lesions may be confused as an odontogenic cyst and should be carefully differentiated from other benign and malignant lesions arising in this region.

Adenomatoid odontogenic tumor (AOT) is a rare noninvasive odontogenic tumor that occurs mostly in the second decade of life. Based on its tooth association, AOT can be classified into three categories of follicular, extrafollicular, and peripheral types; the follicular classification is considered as the most common type of AOT. This study reported a large extrafollicular case of AOT in a 40-year-old female. She was asymptomatic and tumor was detected accidentally by her dental practitioner. Since the panoramic radiograph showed a well-defined unilocular radiolucent lesion, we observed radiopaque spots within the lesion by using cone beam computed tomography. The extrafollicular type can mimic a periapical radiolucent lesion.
