Adenomatoid Odontogenic Tumor: A Case Report.

ABSTRACT

Adenomatoid odontogenic tumor (AOT) is a very rare odontogenic tumor with an incidence of 1%. Overall it accounts for 9% of all odontogenic tumors. In most of the cases, AOT is misdiagnosed as an odontogenic cyst. Younger individuals are commonly affected and particularly in females. AOT is seen predominantly in the maxillary anterior region in association with an unerupted tooth. Permanent dentition is affected more than the deciduous dentition. Intraoral periapical radiographs play a major role in the diagnosis compared to orthopantomogram because of its increased contrast but for the better assessment of the extension of larger lesions orthopantomogram is must. AOT resembles benign odontogenic lesions like dentigerous cyst and tumors like ameloblastoma. The lesions are managed conservatively by surgical excision along with the removal of the affected tooth and have an excellent prognosis.With this background, we report an unusual case of AOT involving maxillary anterior region in 15-year-old male patient. The present article reviews the etiology, clinical features, histopathological features, and treatment modalities of AOT.
