Abstract Adenomatoid odontogenic tumor AOT is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst.
However, all of these reported lesions did not show macroscopically visible pigmentation. Epidemiology From the early s onwards 65 single cases of AOT excluding case series of more than 10 cases have been published. Histologically, the tumor is solid and there is a cyst formation Fig. Open in a separate window. However, the rsview peripheral variant occurs primarily in the gingival tissue of tooth-bearing areas [ 9 ].
