The adenomatoid odontogenic tumor (AOT) is a benign epithelial odontogenic tumor, slow-growing and well-demarcated. The AOT is classified into three variants: follicular, extrafollicular, and peripheral.
1. Follicular Variant
• Definition: The most common form, associated with the crown of an unerupted tooth, often a maxillary canine.
• Key Features:
• Radiographically, it appears as a well-defined radiolucency around the crown, extending along the root.
• Mimics a dentigerous cyst but shows tumor-like behavior.
• Histology reveals duct-like epithelial structures, spindle-shaped cells, and calcifications.
• Differentiation: Distinguished by its tumor-like features and the presence of epithelial duct-like formations.
2. Extrafollicular Variant
• Definition: Occurs independently of unerupted teeth, commonly in the anterior maxilla.
• Key Features:
• Appears as a solitary radiolucency with varying degrees of radiopacity from calcifications.
• Not associated with specific teeth but can cause cortical expansion.
• Histologically identical to the follicular variant.
• Differentiation: Defined by the absence of association with an unerupted tooth.
3. Peripheral Variant
• Definition: The least common, arising in the gingival soft tissues.
• Key Features:
• Appears as a small gingival mass with minimal or no radiographic changes.
• Histologically consistent with other variants, featuring duct-like structures and calcifications.
