Extrafollicular adenomatoid odontogenic tumour.
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.
