title: Calcifying epithelial odontogenic tumors: a clinicopathologic study of nine cases.
abstract: Nine cases of CEOT are reported. There are seven intra-osseous and two extraosseous tumors. All but one occurred in the mandible. The age range was 20 to 64 years; averaging 34.2 years. There were 7 females and 2 males. Radiographically, they appeared either as monocystic or polycystic translucent lesions with radiopaque spots or masses. Embedded teeth were seen in six cases. Microscopically, four different patterns are described. No recurrence has been found postoperatively within 2-14 years of follow-up study. The nature of the reddish homogeneous material, the histogenesis of the tumor and the treatment are briefly discussed.
