Peripheral Ameloblastoma

P eripheral ameloblastomas are rare odontogenic tumors presenting as tumoral masses, erythematous plaques, or papillary lesions on the attached gingiva. This study reviews the demographic, clinical, and microscopic features of 8 previously unreported cases. One patient had two separate peripheral ameloblastomas, one 7 years after the first in the opposite side and arch. The cases match those described previously with respect to age, gender, location, and radiographic and microscopic features. Because recurrence has been reported and second primary sites may be found, periodic followup is recommended after conservative surgical removal. J Periodontol 1995;66:1065–1068 .
