A Rare Case: Adenomatoid Odontogenic Tumor Mimicking Follicular Cyst in a Young Patient
Source abstract
Abstract
The objective of this study is to present an uncommon case of adenomatoid odontogenic tumor (AOT) with an impacted maxillary canine, initially mimicking a follicular cyst. AOT is a rare odontogenic tumor, accounting for approximately 1% to 9% of all odontogenic tumors. It primarily occurs in the maxilla and is often associated with an unerupted permanent tooth. Follicular cysts, also known as dentigerous cysts, are benign odontogenic cysts that encase the crown of an unerupted or impacted tooth. We describe a case of AOT occurring in a 14-year-old male. Both the follicular cyst and adenomatoid odontogenic tumor (AOT) can exhibit similar clinical and radiographic presentations. It is crucial to accurately differentiate between the two to ensure appropriate treatment and prognosis.
