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.

ABSTRACTAdenomatoid odontogenic tumor (AOT) is a rare tumor comprising only 3% of all odontogenic tumors. It is a benign, encapsulated, noninvasive, nonaggressive, slowly growing odontogenic lesion associated with an impacted tooth. These lesions may go unnoticed for years. The usual treatment is enucleation and curettage, and the lesion does not recur. Here, we present a rare case of an unusually large aggressive AOT of maxilla associated with impacted third molar. The authors also discuss clinical, radiographic, histopathologic, and therapeutic features of the case. Subtotal maxillectomy with simultaneous reconstruction of the surgical defect with temporalis myofascial flap was planned and carried out.

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.
