Peripheral ameloblastic fibro-odontoma-Report of 2 cases of a very rare entity

Abstract

Ameloblastic fibro-odontoma (AFO) is a rare benign mixed odontogenic tumor that affects children and young adults. AFO occurs mainly intraosseous. Extraosseous AFO is extremely rare. We report 2 cases of rare peripheral ameloblastic fibro-odontoma in 2- and 12-year-old female patients. Microscopic examination revealed a benign proliferation of odontogenic epithelium associated with a dentinoid material distributed within a cell-rich mesenchymal stroma resembling dental papilla. Simple surgical excision of the lesion is usually curative. There was no recurrence after a short period of follow-up. Clinicians should be cognizant of this rare entity, which can be considered in a differential diagnosis of gingival growths that are noted in early childhood.
