Abstract

Adenomatoid odontogenic tumor [AOT] is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. AOT accounts for about 1% until 9% of all odontogenic tumors. It is predominantly found in young female patients, located more often in maxilla and most often associated with an unerupted permanent tooth. However, AOT frequently resemble other odontogenic lesions such as dentigerous cysts or ameloblastoma. For illustration a rare case of an AOT in the mandible in a 12-year-old female patient is presented

Highlights

Odontogenic tumors are lesions that derive from the toothproducing tissues or their remnants that remain entrapped either within the jawbones or into the adjacent soft tissues
It is known that the potential sources to develop an odontogenic tumor are varied, and these include: 1. The pre-functional dental lamina [odontogenic epithelium with ability to produce a tooth], which is more abundant for obvious reasons distally to the lower third molars
Adenomatoid odontogenic tumor [AOT] is a relatively uncommon distinct odontogenic neoplasm comprises only 0.1 per cent of tumors and cysts of the jaw and 3 per cent of all odontogenic tumours [4]

Summary

Introduction

Odontogenic tumors are lesions that derive from the toothproducing tissues or their remnants that remain entrapped either within the jawbones or into the adjacent soft tissues. It is known that the potential sources to develop an odontogenic tumor are varied, and these include: 1. The pre-functional dental lamina [odontogenic epithelium with ability to produce a tooth], which is more abundant for obvious reasons distally to the lower third molars. 2. The post functional dental lamina, a concept that covers those epithelial remnants such as Serres epithelial rests, located within the fibrous gingival tissue; the epithelial cell rests of Malassez in the periodontal ligament and the reduced enamel organ epithelium, which covers the enamel surface until tooth eruption. The extra follicular variant has neither a pericoronal nor any other relationship to an embedded tooth. I am presenting a clinico-pathological observation of the extra-follicular variety of this infrequent benign tumor, affecting the anterior area of the mandible, in a 12-year-old patient
