Peripheral adenomatoid odontogenic tumour: Case report and review of literature

The peripheral adenomatoid odontogenic tumour is an uncommon subtype of adenomatoid odontogenic tumour (AOT).It has a female preponderance commonly in theage group of 3-25 years. Anterior maxilla is themost frequent site of involvement. Clinically, it is manifested as soft tissue mass on gingiva with infrabony pocket and minimum bone involvement. So this lesion is easily misdiagnosed by the clinician as simple gingival growth.Histopathological features are identical to that of their intra-osseous counterpart.We present a case of 27 years old female who had her lesion on the gingiva of right maxillary canine region which is notausual site of involvement. Few cases have been reported in the literature but all exclusively involved the gingiva of maxillary incisors. In this context extensive study is needed to figure out the exact site distribution and clinical presentation of the disease.
