Calcifying epithelial odontogenic tumor of the maxilla.

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign neoplasm; it comprises only 0.6 % to 1.7 % of all odontogenic tumors. Most cases involve the posterior mandible; there have been few reported maxillary cases. Although its biological behavior is relatively indolent, maxillary lesions tend to grown rapidly and not be circumscribed. Treatment of the CEOT consists of surgical removal, ranging from a conservative approach to a more aggressive resection. A 14% local recurrence rate has been reported; the prognosis is considered as faborable.
