An aggressive presentation of adenomatoid odontogenic tumor associated with calcifying epithelial odontogenic tumor: A hybrid variant

Abstract

The adenomatoid odontogenic tumor (AOT) was formerly considered to be a variant of the ameloblastoma and was designated as adenoameloblastoma. It represents 3-7% of all odontogenic tumor and over 750 cases have been reported in the literature. Though this lesion shows pathognomic histological features, few overlapping patterns of the odontogenic tumors may be seen. AOT may infrequently show additional areas resembling to calcifying epithelial odontogenic tumor. Long-term follow-up research is need of the hour for such hybrid histological combination effect on the locally aggressive nature of the lesion. We present a case of a follicular variant of AOT in a 22 years male presenting with swelling on anterior maxilla associated with impacted canine.
