Adenomatoid and calcifying epithelial odontogenic tumors.

The histologic diversity of the odontogenic epithelium's neoplasms is nicely illustrated by the adenomatoid and the calcifying epithelial odontogenic tumors. The former has a predilection for the maxilla, the latter for the mandible. Neither has a malignant variant, and each is controlled by conservative local removal. The recurrence rate of the adenomatoid odontogenic tumor is 0.2%, while the calcifying epithelial odontogenic tumor's rate is 14%.
