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.

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.

Abstract Introduction/Objective Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic tumor representing 3 to 7% of all odontogenic tumors. This tumor was first reported as adeno-ameloblastoma by Bernier and Tiecke in 1950 as it was initially assumed to be a type of ameloblastoma. In 1969, Philipsen and Bern proposed the term adenomatoid odontogenic tumor which was subsequently adopted by WHO and became the accepted terminology for this tumor. AOT is classified as a tumor of odontogenic epithelium but occasionally abnormal hard tissues consistent with dentinoid material may also be present as part of the tumor. AOT tends to occur in younger patients and 50% of the cases are diagnosed in teenagers. It occurs twice as commonly in females and frequently involves the anterior maxilla. Radiographically, AOT can appear as a radiolucent or mixed lucent-opaque lesion and may be associated with an impacted tooth. Methods/Case Report We report two unusually large expansile lesions of AOT that presented in the mandible. In the first case, the tumor presented as an expansile radiolucent lesion involving the right posterior mandible in a 32 year old female. In the second case, the tumor presented as an expansile mixed lucent-opaque lesion involving the left anterior mandible in a 21 year old female. The clinical presentation, radiographic and imaging findings, histopathologic features and treatment of these two cases will be discussed. The recommended treatment for AOT is surgical excision. The prognosis is good as this tumor seldom recurs after excision. Results (if a Case Study enter NA) NA Conclusion AOT is considered to be a non-aggressive, non-invasive and slow growing benign neoplasm. It is usually discovered on routine radiographic examination as the lesion is usually small and asymptomatic at the time of diagnosis but occasional cases that are larger in size have been reported in the literature.

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

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.

Adenomatoid Odontogenic Tumour

The adenomatoid odontogenic tumor (AOT) is a relatively uncommon lesion which mainly affects females in their second decade of life, exhibiting predilection for the anterior region of the maxilla. The lesion is usually associated with the crown of an enclosed tooth, most commonly the maxillary canine. In this paper we present a case of adenomatoid odontogenic tumor associated with a dentigerous cyst affecting the left maxilla in a 15-year-old female. We also discuss clinical, radiographic, histopathologic, and therapeutic features of the case.
