EXTRAOSSEOUS CALCIFYING EPITHELIAL ODONTOGENIC-TUMOR - REPORT OF 2 CASES AND REVIEW OF THE LITERATURE

In this study two additional cases of extraosseous calcifying epitheli al odontogenic tumor are reported, both of which exhibited a prominent clear cell component. The clinical and histopathologic findings of th ese two cases are compared with those of the nine reported cases from the English language literature. The age range for the 11 cases was 12 to 64 years with a mean age of 34.4 years at the time of diagnosis. S ix of the tumors involved female patients and five involved male patie nts. Seven cases were located on the mandibular gingiva with the remai ning four cases involving the maxillary gingiva. On microscopic evalua tion, six of the lesions exhibited a predominant clear cell component. Appropriate management of the extraosseous calcifying epithelial odon togenic tumor consists of simple excision. No recurrences have been re corded.
