ADENOMATOID ODONTOGENIC-TUMOR WITH FEATURES OF CALCIFYING EPITHELIAL ODONTOGENIC-TUMOR - (THE SO-CALLED COMBINED EPITHELIAL ODONTOGENIC-TUMOR) - CLINICOPATHOLOGICAL REPORT OF 12 CASES

The combination of two odontogenic tumours is a rarely reported findin g. To date only 10 cases of adenomatoid odontogenic tumour (AOT) combi ned with areas of calcifying epithelial odontogenic tumour (CEOT) have been published. This article describes the clinical, radiographical a nd microscopic findings of 12 cases of AOT, in which CEOT-like areas o f variable sizes were found. These results suggest that such areas may be considered as a normal feature within the histomorphological spect rum of AOT.
