Adenomatoid odontogenic tumor (AOT) is a rare noninvasive odontogenic tumor that occurs mostly in the second decade of life. Based on its tooth association, AOT can be classified into three categories of follicular, extrafollicular, and peripheral types; the follicular classification is considered as the most common type of AOT. This study reported a large extrafollicular case of AOT in a 40-year-old female. She was asymptomatic and tumor was detected accidentally by her dental practitioner. Since the panoramic radiograph showed a well-defined unilocular radiolucent lesion, we observed radiopaque spots within the lesion by using cone beam computed tomography. The extrafollicular type can mimic a periapical radiolucent lesion.
腺牙源性肿瘤（AOT）是一种罕见的非侵袭性牙源性肿瘤，多发生于生命的第二个十年。根据其与牙齿的关联，AOT可分为滤泡型、滤泡外型和周边型三类；滤泡型被认为是AOT最常见的类型。本研究报告了一例40岁女性的大型滤泡外型AOT病例。她没有症状，肿瘤是由她的牙医偶然发现的。由于全景X线片显示有一个边界清晰的单房透射性病变，我们使用锥形束计算机断层扫描在病变内观察到了不透射线的斑点。滤泡外型可能会模仿根尖透射性病变。
