  • Title: Ameloblastoma suggesting large apical periodontitis.
    Author: Faitaroni LA, Bueno MR, De Carvalhosa AA, Bruehmueller Ale KA, Estrela C.
    Journal: J Endod; 2008 Feb; 34(2):216-9. PubMed ID: 18215686.
    Abstract:
    This case report describes the endodontic treatment of a large apical periodontitis with well-defined margins adjacent to teeth #22-24. After the initial endodontic treatment, continued expansion of the mandible cortical bone was observed, indicating a need to surgically enucleate the lesion and submit it for histopathologic examination. The microscopic examination indicated a diagnosis of ameloblastoma. Ameloblastoma is a benign epithelial neoplasm of odontogenic origin, and depending on the stage of development, it can mimic a periapical lesion and therefore should be considered in establishing an endodontic differential diagnosis. The definitive diagnosis for some periapical lesions can only be made by a histopathologic examination.
