Extrafollicular Cystic Adenomatoid Odontogenic Tumor Misdiagnosed as Glandular Odontogenic Cyst

Adenomatoid odontogenic tumor (AOT) is a benign slow-growing, asymptomatic epithelial odontogenic neoplasm. This lesion has been known for its varied clinical and histoarchitec-tural patterns. Most AOTs occur intra-osseously in the anterior maxilla associated with the unerupted tooth. Clinically, AOT is sometimes misdiagnosed as an odontogenic cyst. Alt-hough enucleation and curettage for AOT is the most common treatment modality, accurate histopathological diagnosis is essential to avoid unnecessary extensive surgery. Here, we present a rare challenging case of an extrafollicular cystic adenomatoid odontogenic tumor occurring in the body of the mandible in a 23-year-old female patient, which was diagnosed clinically and radiographically as glandular odontogenic cyst. The diagnosis of adenomatoid odontogenic tumor was confirmed through histopathological examination
