Abstract Adenomatoid Odontogenic Tumour (AOT) is an unusual benign tumour unique to maxillofacial area, with a tendency to involve the tooth bearing areas of both the jaws and accounting for 3% of all the odontogenic tumours. Diagnosis of the tumour is sometimes intriguing owing to its variable clinical and radiographic presentation. One such variable and relatively rare presentation of extrafollicular type of adenomatoid odontogenic tumour in anterior maxilla of an eighteen year old female has been discussed in this paper which can be refreshing for the practitioner.

Adenomatoid Odontogenic Tumour

Adenomatoid Odontogenic Tumour (AOT) is odontogenic epithelial tumour, also known as pseudoadenoameloblastoma/adenoameloblastoma, which was described by Dreibaldt in 1907 [1]. The term “Adenomatoid odontogenic tumour” was proposed by Philipsen et al [2] indicating that it was not a variant of ameloblastoma. In the World Health Organization classification of odontogenic tumours established in 1971, AOT was mentioned as a mixed odontogenic neoplasm, an epithelial tumour with an inductive effect on the odontogenic mesenchyme [3].It represents 3–7% of all odontogenic tumours largely limited to younger patients and striking tendency to occur in anterior maxilla, and over 750 examples have been reported in the literature [4]. This case report presents a case of an Adenomatoid Odontogenic Tumour in the left maxillary anterior region which was diagnosed using radiographs and removed by surgical excision.

Adenomatoid odontogenic tumour, truly coined as one of the masters of disguise of orofacial pathologies, was first reported in the literature by Steen Lands.1 Philipson and Brin used the terminology adenomatoid odontogenic tumour for this pathology with its commonly accepted abbreviation AOT.2 Later on, adenomatoid odontogenic tumour (AOT) name was accepted by the World Health Organization (WHO) in 1971. In 2005, WHO revealed the histological variants of the adenomatoid odontogenic tumour and classified it as a tumour comprised of odontogenic epithelium showing various patterns in histopathologic view within a mature connective tissue stroma.3 It is seldom noticed neoplasm which comprises only 3 % of all the odontogenic tumours. It was commonly found in the maxilla with female predilection and mostly in association with impacted canines.4-6 Adenomatoid odontogenic tumour is an odontogenic epithelial tumour usually seen in females in their second decade of life. The tumour is slow growing in nature which eventually results in painless expansion of jaw. The maxilla is commonly affected than mandible. Being benign in nature, most of the AOT cases usually got treated with conservative surgical enucleation but the greater size of tumour can leave behind an oro-facial defect. To prevent such type of incident, it is important to diagnose them early and treat accordingly. Herewith, we are presenting a case report of adenomatoid odontogenic tumour of mandible in a male patient.

Adenomatoid odontogenic tumour (AOT) is a rare tumour of odontogenic origin with distinct clinicopathological appearance but is often clinically misdiagnosed as a cyst. The most common site is the anterior maxilla in the canine region. We present here two cases, one at its commonest location in the maxillary canine while the other is at the uncommon location of the anterior mandible. Its clinical features of painless slow growing swelling, association with impacted tooth and radiographic appearance of well defined predominantly radiolucent lesion are overlapping with other oral pathologies like dentigerous cyst, radicular cyst, calcifying odontogenic cyst, calcifying epithelial odontogenic tumour, unicystic ameloblastoma etc. One must be aware and updated with the variation in appearance of AOT. Encapsulation of tumour causes less cumbersome enucleation of the tumour, a successful treatment as it reduces the chances of recurrence.

Adenomatoid Odontogenic Tumour

ABSTRACT Adenomatoid odontogenic tumour is a relatively uncommon odontogenic tumour first described by steensland in 1905. Adenomatoid odontogenic tumour accounts for about 3-7% of all odontogenic tumours, predominantly found in young female patients, located more often in maxilla associated with an unerupted permanent tooth. The tumour often misdiagnosed as an odontogenic cyst. AOT frequently resembles other odontogenic lesions such as dentigerous cysts or ameloblastomas. Therefore, it should be distinguished from the more common lesions of odontogenic origin in routine dental examinations. We present a rare case report of 59-year-old female patient of AOT occurring in the maxilla.
