Concomitant occurrence of cemento-ossifying fibroma and adenomatoid odontogenic tumor with bilateral impacted permanent canines in the mandible.

ABSTRACT

Adenomatoid odontogenic tumor (AOT) is an uncommon, benign and slow growing odontogenic tumor, which is usually located in an anterior region of the maxilla without pain. Cemento-ossifying fibroma (COF) is a relatively rare benign tumor of the jaw. Here we present 2 lesions presenting in unusual forms, follicular variant of AOT in the mandible and COF associated with impacted canine in the mandible, occurring concomitantly in the same patient. Both lesions presented classic histopathologic features.
