Adenomatoid Odontogenic Tumour Mimicking Dentigerous Cyst Associated with Mandibular Lateral Incisor: An Unusal Case

Abstract

Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. This clinical entity has been regarded as a benign odontogenic tumor, sharing its clinical and radiographic features with those of dentigerous cysts. It is a slow growing, non-invasive benign lesion of odontogenic epithelial origin. The maxilla is more afflicted than the mandible, and the anterior part of the jaw is more persistantly involved than the posterior part.. An impacted maxillary canine is the most common tooth to be associated with an adenomatoid odontogenic tumor (AOT).Here is a case report of a 16 year old girl who presented with a well defined unilocular radiolucency involving an impacted mandibular lateral in the anterior mandible, which resembled a dentigerous cyst.  Enucleation done and excised lesion was histopathologically confirmed to be an Adenomatoid odontogenic tumor (AOT)
