Metrics details Abstract Adenomatoid odontogenic tumor AOT is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional information about AOT, all reports regarding AOT and cited in "pubmed" since onward were reviewed. It is predominantly found in young and female patients, located more often in the maxilla in most cases associated with an uneruppted permanent tooth. For radiological diagnose the intraoral periapical radiograph seems to be more useful than panoramic. However, AOT frequently resemble other odontogenic lesions such as dentigerous cysts or ameloblastoma.

This lesion is most commonly located in the anterior maxilla and is usually associated with an impacted canine tooth. This is a case report of a year-old female patient presented with a large AOT of the posterior maxilla associated with an impacted second molar — a very rare situation.

Unal et al. Terms such as adeno ameloblastoma, ameloblastic adenomatoid tumor, adamantinoma, epithelioma adamantinum or teratomatous odontoma have been used before to define the lesion which is currently known as AOT. It was Stafne in who considered it as a distinct entity. This is a report of a large follicular AOT associated with a dentigerous cyst in the posterior maxilla in association with an impacted second molar- a very rare occurrence, which was mistaken for a dentigerous cyst clinically and radiographically.

CASE REPORT A year-old female patient reported to my dental clinic with a chief complaint of pain and swelling over left side of upper jaw of 1month duration with mobility of her upper last tooth. On examination of the patient, she had a diffuse extra-oral swelling measuring approximately 1. There was no paraesthesia over infraorbital region. Intraoral examination revealed a soft fluctuant swelling on left side maxilla extending from left upper premolar to third molar region, obliterating the buccal vestibule.

Left upper first and second molars were missing, left upper third molar showed grade 3 mobility. Mucosa overlying the swelling was normal. On aspiration, straw-colored fluid was obtained. On the basis of clinical and radiographical findings, the differential diagnosis were dentigerous cyst, unicystic ameloblastoma and AOT.


Adenomatoid odontogenic tumor of the mandible: review of the literature and report of a rare case

E-mail: moc. This article has been cited by other articles in PMC. Abstract Here we report a case of adenomatoid odontogenic tumor AOT in the maxilla in a young girl aged 14 years and its surgical management. We also review the literature and variations in the nomenclature and classifications of this interesting tumor. The review of literature gives an interesting picture regarding terminologies in the past and dilemma in classifying this tumor. The introduction of the name adenomatoid odontogenic tumour has resulted in the simpler and fruitful surgical management like enucleation and curettage with no reports of recurrences. In the past, similar lesion with the terminology like adeno ameloblastoma has resulted in unnecessary mutilating surgery.


Adenomatoid odontogenic tumor, an uncommon tumor

Abstract Adenomatoid odontogenic tumor AOT has a limited biological profile and been an attention-grabbing tumor for a century for its origin. Though described earlier, it was widely accepted after Harbitz from Norway reported about this uncommon benign tumor in There has been a long debate as whether this tumor is a hamartoma or a neoplasm. Here, we present a case of AOT in a year-old female with details of clinical, radiological and histological features along with clear cell changes, signifying AOT to be more aggressive in nature than assessed from earlier literature. Thus, we did an extensive search of PubMed literature on AOT with all its histopathological features associated until date to find the report of clear cell changes yet. Adenomatoid odontogenic tumor with clear cell changes.
