Ameloblastoma originated from a dentigerous cyst: a case report

• Shin JM

Abstract

Much has been written about the possibility that the lining of a dentigerous cyst might undergo neoplastic transformation to an ameloblastoma which is defined as mural ameloblastoma. Mural ameloblastomas are estimated to constitute 5% of all ameloblastomas. 85 % of the mural ameloblastomas were associated with dentigerous cyst, all of which were observed before the age of 30. The frequency of recurrence after simple enucleation of the cyst containing this lesion is considerably lower than that for ameloblastomas in general that are treated in a similar manner. Therefore, further and more extensive surgery is not required for mural ameloblastoma. We diagnosed a cystic appearance of a 17 year-old female as dentigerous cyst and undergone marsupialization. For 2 years of period, no significant change was observed and therefore enucleation was undergone and diagnosed as ameloblastoma. We report this case with a review of related literatures.
