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.

Background. Adenomatoid Odontogenic Tumor (AOT) is a rare tumor of epithelial origin. AOT appears in three clinico-topographic variants: follicular, extrafollicular and peripheral. The AOT was predominantly found in the upper jaw, and rarely found in mandible, especially at anterior mandible. AOT is a tumor of odontogenic epithelium having duct like structures, which may be partly cystic, and in some cases the solid lesion may be present only as masses in the wall of a large cyst. The surgical management of this lesion would be enucleation along with removal of associated impacted tooth. The prognosis for both of them is good and recurrences are very rare after complete removal of the lesion. Purpose. It is important to define final diagnose for AOT due to mimicking with DC in clinically and radiographically finding. Biopsy is still obviously necessary to the final diagnosis. Case. 15-year-old female patients reported with chief complain of swelling in anterior mandible. The swelling beginning 4 years ago, gradually progressed, with no history pain, discharge and patient is complaint about loss of sensation around anterior mandible. Aspiration revealed straw colored fluid thinking in the way of DC. The provisional diagnosis of DC was given due to clinical presentation and radiographic imaging. But the biopsy examination showed AOT due to duct-like epithelial cells was being found. Discussion. The case report illustrates characteristic clinical and radiographic features of follicular variant of AOT mimicking a DC at unusual site that is anterior mandible. AOT is thought to arise from odontogenic epithelium and associated with the impacted tooth. Rightfully AOT is a perfect imitator of DC radiographically as well as histopathologically. It usually clinically misdiagnosed as DC as both have a unilocular, well-defined radiolucency surrounding the crown of an impacted tooth. The mass was enucleated, involved teeth were extracted, and titanium plates are used to avoid pathologist fracture. The patient had uneventful postoperative recovery. Follow up of a year has not shown any evidence of recurrence. Conclusion. Follicular type of OAT could confuse us with DC if the support examination just only clinicaly finding and radiographic examination. This case could not be definitively diagnosed on clinical and radiographic features alone. Biopsy was obviously necessary to the final diagnosis.

ABSTRACT The odontogenic keratocyst (OKC) has recently been reclassified by the WHO (2005), as keratocystic odontogenic tumor (KCOT) based on clinical, histological and immunohistochemical parameters. KCOT more commonly occurs in the mandible and cases involving the maxilla are infrequent. We report an unusual and rare case of a KCOT of the maxilla in a middle-aged individual with extensive involvement and displacement of the maxillary third molar to the zygomatic region. A discussion of the parameters involved in the reclassification of the lesion as a tumor is presented alongwith a review of literature.
