Extrafollicular Variant of the Common Adenomatoid Odontogenic Tumour: A Rare Case Report

Adenomatoid odontogenic tumour (AOT) is a benign epithelial neoplasm of odontogenic origin, typically seen in young female patients and commonly associated with impacted canines in the anterior maxilla. The extrafollicular variant, which is not associated with unerupted teeth, is relatively rare and may present diagnostic challenges due to its similarity with other odontogenic cysts or tumours. This report presents a case of a 23-year-old female patient with a gradually enlarging swelling in the anterior maxilla. Radiographic imaging revealed a well-defined radiolucency with root resorption and displacement of adjacent teeth. Histopathological examination confirmed the diagnosis of extrafollicular AOT. The lesion was managed successfully with conservative surgical excision, and no recurrence was noted during a two-year follow-up. This case highlights the importance of integrating clinical, radiological, and histopathological findings for accurate diagnosis and appropriate management of this rare AOT variant.
