ADENOMATOID ODONTOGENIC TUMOR ASSOCIATED WITH CALCIFYING EPITHELIAL ODONTOGENIC TUMOR: A CASE REPORT

Abstract

Adenomatoid Odontogenic Tumors (AOT) make up 3% of all odontogenic tumors. The most conspieuous feature of this tumor is nodules or wholes of spindle-shaped of cuboidal epithelial cells. Within these cellular areas, ductiform structures formed by cuboidal or low columnar cells may be identified. Between the epithelial cells, there apear some focl of calcification mimieing cellular featurs of Calcifying Epithelial Odontogenic Tumor (CEOT). However, combination of cellular features of these two different odontonogenic tumors is a very rare finding. Here, a case of a so-called Combined Epithelial Odontogenic Tumor, associated with an impacted mandibular canine, is presented in a 16 year-old white male. Under local anesthesia, the tumor and the tooth were removed. The histopathological examination revealed that the tumor to be consisting primarily of AOT with some areas of CEOT. Healing was uneventful No recurrence was detected at two years time period.
