Abstract
The adenomatoid odontogenic tumour is a relatively uncommon lesion which mainly affects females in their second decade of life. It exhibits a predilection for the anterior region of the maxilla. The lesion is usually associated with the crown of an embedded tooth, most commonly the maxillary canine. In this paper, we present a case of adenomatoid odontogenic tumor affecting the left maxillary region in a 24-year-old female. The authors also discuss clinical, radiographic, histopathologic, and therapeutic features of the case.
Highlights
The adenomatoid odontogenic tumor (AOT) represents 3%– 7% of all odontogenic tumors and was once considered as a variant of ameloblastoma
According to the clinical and surgical findings, the lesion was diagnosed as an odontogenic cyst
The differential diagnosis was of dentigerous cyst, calcifying odontogenic cyst, calcifying epithelial tumor, odontogenic keratocyst, and unicystic ameloblastoma
Summary
The adenomatoid odontogenic tumor (AOT) represents 3%– 7% of all odontogenic tumors and was once considered as a variant of ameloblastoma. AOT is a circumscribed lesion with slow growth. A few extraosseous variants of AOT have been reported. The Armed Forces Institute of Pathology (AFIP) in United States of America has described a similar neoplasm with recurrence potential and suggested the term “adenoid ameloblastoma with dentinoid” for these lesions [4]. A 24-year-old Indian female was referred by her general practitioner for evaluation of a maxillary swelling to Department of Oral Medicine, Faculty of Dental sciences, Institute of Medical Sciences, Banaras Hindu University. An orthopantomogram revealed the presence of a significant unilocular radiolucent area with well-defined sclerotic borders, involving an embedded upper left permanent canine
