Adenomatoid Odontogenic Tumor – A Case Report

Adenomatoid odontogenic tumor, a benign tumor of odontogenic origin has known for many years. Only few case reports have been published in the literatute and hence considered to be an uncommon tumor. The lesion has been called by various names as it has exhibited in various clinical and histological patterns for which the origin and histogenesis still remains uncertain. Here, we report a case of 18 year old female patient who came to us with a complain of swelling in the upper anterior tooth region and radiographically showing an Extrafollicular radiolucency adjacent to the crown of an impacted canine tooth.

Uncommon Tumor

Adenomatoid odontogenic tumor (AOT), a benign (hamartomatous) lesion of odontogenic origin, is an uncommon tumor which affects mainly females in the second decade. This lesion is most commonly associated with an impacted maxillary canine. This paper reported a case of AOT, in a 16-year-old female, associated with an impacted maxillary left lateral incisor. The evolution of this tumor was followed over 36 months and 24 months after excision.

Uncommon Tumor

ABSTRACT Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, constituting only 3% of all odontogenic tumors. AOT is characterized histologically by the formation of duct-like structures with amyloid-like deposits. An 18-year-old male presented with right chek swelling. CT scan revealed well-defined expansile heterogeneous mass with central hypodensity. Patient underwent excision of the mass by Caldwell-luc approach and histopathologically the diagnosis adenomatoid odontogenic tumor was made. Since it is a benign tumor, the treatment should consist of enucleation and curettage.

Epithelial Lesion

Adenomatoid Odontogenic Tumor (AOT) is a well-established benign epithelial lesion of odontogenic origin. Rightfully called “the master of disguise,” this lesion has been known for its varied clinical and histoarchitectural patterns. Not only does AOT predominantly present radiologically as a unilocular cystic lesion enclosing the unerupted tooth (which is commonly mistaken as a dentigerous cyst) but the lesion also presents rarely with a cystic component histopathologically. We present one such unusual case of cystic AOT associated with an impacted canine, mimicking a dentigerous cyst. The present case aims to highlight the difference between cystic AOT and dentigerous cyst radiographically. The exact histogenesis of AOT and its variants still remains obscure. An attempt has been made to hypothesize the new school of thought regarding the origin of AOT.

Slow Growing

Adenomatoid odontogenic tumor is a rare benign odontogenic tumor comprising of 3% to 7% of all Odontogenic tumors. It is usually asymptomatic, well circumscribed, slow growing tumor associated often with impacted canine and discovered on routine radiographs. Microscopically this lesion shows a variety of patterns forming sheets, strands, nest or rosette-like structures with ductal pattern with central space surrounded by single layer of cuboidal to columnar epithelial cells with a rim of eosinophilic coagulum which is the characteristic feature of these tumors. In this article we present two extrafollicular cases of this rare tumor occurring in a male and a female patient in the maxillary anterior region with both symptomatic and asymptomatic presentation. Both the tumors were not associated with any impacted tooth. Adenomatiod Odontogenic tumor was confirmed based on histopathology.

True Neoplasm

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, characterized histologically by the formation of ductlike structures with amyloid-like deposits. Histogenesis of AOT is still uncertain and it is often considered as a hamartomatous lesion rather than a true neoplasm. AOT has a benign behavior and conservative surgical enucleation or curettage is sufficient. We report a case of AOT in a 15-year-old female who presented with left-sided jaw swelling with tooth resorption. Histopathology revealed intraosseus follicular variant of AOT. A brief review of literature is also discussed.
