Peripheral ameloblastoma: a report of 2 cases.

Peripheral ameloblastoma (PA) is a rare odontogenic tumor most common in elderly patients. They are usually solitary; red or pink granular, nodular, or papillary lesions; up to 1.5 cm in diameter; and either not resorb bone or produce a shallow erosion. Peripheral ameloblastoma should be included in the differential diagnosis of soft tissue lumps on the gingiva or edentulous alveolus.
