<p class="abstract"><span lang="EN-IN">We report a case of adenomatoid odontogenic tumor (AOT) in the maxilla in a boy aged 17 years. AOT is an odontogenic tumour arising from the enamel or dental lamina.  AOT is rare and it represents 3–7% of all odontogenic tumors. This lesion affects young girls and is associated with an impacted tooth, usually canine. This case is presented to highlight the presentation of the tumour in a male patient and in an uncommon site, the left upper 1st molar. Differentiating this benign tumor from other lesions is difficult before surgical management and histopathological examination is important in accurate diagnosis. </span><span lang="EN-IN"> </span></p>

Adenomatoid odontogenic tumor (AOT) is a well-recognised slow growing benign tumor derived from complex system of dental lamina or its remnants. This lesion is categorised into three variants of which the more common variant is follicular type which is often mistaken for dentigerous cyst. We present a case of AOT in a 14-year-old male who was misdiagnosed as dentigerous cyst. Clinical radiological and therapeutic characteristics of the case are commented on in detail.

Adenomatoid Odontogenic Tumour

Adenomatoid Odontogenic Tumour (AOT) is a relatively uncommon benign odontogenic tumour composed of odontogenic epithelium in a variety of histoarchitectural patterns. Conventional AOT is predominantly seen in females in second decade of life exhibiting predilection for anterior region of maxilla. Very few cases of AOT associated with dentigerous cyst have been reported till date. The present case is unique associated with an impacted lower first premolar in the front region of the mandible of an 18-year-old female patient. The patient reported to the institute with gradually increasing swelling. The orthopantomogram revealed a unilocular radiolucency with displaced premolar. Histopathological examination confirmed 4×2.5×2 cm lesion in dimension, brownish black in colour, firm in consistency with a smooth surface grossly while cut surface revealed a cystic lumen with an impacted premolar embedded into the lining, cystic wall being nodular. Microscopic evaluation revealed a well encapsulated lesion with a thin 2-3 cell layered non keratinised stratified epithelial lining in patterns such as nests, rosette like structures and duct like structures. Thus the diagnosis of AOT arising from dentigerous cyst was confirmed. Patient's six month follow-up was uneventful. Literature search of similar cases with the review of hypothesised aetiopathogenesis is discussed in brief. The available data can help researchers resolve the uncertainty whether the AOT derived from dentigerous cyst could represent a distinct hybrid variety.

Adenomatoid odontogenic tumour (AOT) is a rare tumour of odontogenic origin with distinct clinicopathological appearance but is often clinically misdiagnosed as a cyst. The most common site is the anterior maxilla in the canine region. We present here two cases, one at its commonest location in the maxillary canine while the other is at the uncommon location of the anterior mandible. Its clinical features of painless slow growing swelling, association with impacted tooth and radiographic appearance of well defined predominantly radiolucent lesion are overlapping with other oral pathologies like dentigerous cyst, radicular cyst, calcifying odontogenic cyst, calcifying epithelial odontogenic tumour, unicystic ameloblastoma etc. One must be aware and updated with the variation in appearance of AOT. Encapsulation of tumour causes less cumbersome enucleation of the tumour, a successful treatment as it reduces the chances of recurrence.

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.

Background: Hemolymphangioma is a rare benign tumor. To the best of our knowledge, there were only 10 reports of this tumor of the pancreas until March 2018. Case Report: Here, we reported a large invasive hemolymphangioma of the pancreas in a young woman with a complaint of abdominal distension and an epigastric mass about 3 weeks. She was found to have a huge multilocular cystic tumor at the neck and body of pancreas on computed tomography. She was eventually diagnosed with hemolymphangioma of the pancreas after operation. After 2 years of follow-up, there was no signs of recurrence. Conclusion: From our case and literature, we can conclude that hemolymphangioma of the pancreas is uncommon benign tumor, and it is hard to make an accurate diagnosis preoperatively. Radical surgical resection should be performed whenever possible. The prognosis of this disease seems good.

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.
