This tumor most commonly occurs in the maxilla, in the age range of 3–82 years and has a female predilection. Most AOTs occur intraosseously, while few occur within gingival structures. AOT located intraosseously may/may not be associated with an unerupted tooth (extrafollicular variant). This article highlights the unusual presentation of AOT seen in an 11-year-old female patient with a history of trauma 4 years back and a noticeable swelling in the same region 2 years later. The clinical findings were suggestive of traumatic bone cyst, fibroma, central ossifying fibroma, central giant cell granuloma (CGCG), and odontogenic tumor. Based on the radiological features, a differential diagnosis of central ossifying fibroma, CGCG, fibrous dysplasia, and extrafollicular variant of AOT/odontogenic tumor was given. Eventually, radiographic and histopathologic investigations confirmed the case as an extrafollicular variant of AOT. ER -
