Adenomatoid Odontogenic Tumor Arising from the Lower Central Incisor—A Case Report

Abstract

Adenomatoid odontogenic tumor (AOT) is a relatively uncommon tumor that accounts for 2.2–7% of all odontogenic tumors. 59% of the AOTs are found in relation to impacted canines, of which around 40% are associated with maxillary canines. We describe a case of AOT where a patient reported to us with the chief complaint of missing permanent teeth in the lower front region. Orthopantomograph showed a well-defined uniocular radiolucent lesion extending from the mesial aspect of 31 till the mesial aspect of 44. A differential diagnosis of AOT, calcifying cystic odontogenic tumour (CCOT) or unicystic ameloblastoma was made. The patient underwent enucleation of the lesion under general anesthesia. Introperatively, the crown of central incisor was projecting out of the lesion and the root was found to be embedded in the lesion. Histopathologically the features were suggestive of AOT. The clinician must be aware that although a rare finding, AOT can arise from a lower central incisor.
