Peripheral Ameloblastoma with Interdental Bone Loss: A Rare Case Report Running title : Peripheral ameloblastoma a rare case report

The peripheral ameloblastoma (PA) is a rare, benign, extraosseous odontogenic soft tissue tumour that is confined to the gingiva or alveolar mucosa. The PA presents the same histological characteristics of intraosseous ameloblastoma, although it is less aggressive than this classical subtype. A 47-year-old non-smoker male patient reported to Department of Periodontics, SCB Dental College and Hospital, Cuttack with an asymptomatic lesion on the buccal gingiva of the canine-premolar-molar right mandibular region growing slowly for the last 1 year. Thorough clinical examination was carried out. Incisional biopsy, histopathological and radiographic investigation with CBCT was done for the lesion followed by excision of the lesion. In this report we present a clinical case of PA of the in the right mandibular gingiva, highlighting the importance of histological examination to the diagnosis.
