Synchronous Calcifying Epithelial Odontogenic Tumor: Case Report and Analysis of the 5 Cases in the Literature

Abstract

Calcifying epithelial odontogenic tumor (CEOT), or Pindborg tumor, is infrequent and accounts for less than 1% of all odontogenic tumors. It is benign and usually asymptomatic but displays locally infiltrative and expansile behavior. Synchronous lesions affecting the jaws are exceedingly rare. We present a case of synchronous CEOTs affecting the maxilla and mandible and describe the clinical, radiographic, histologic, and immunohistochemical features. We further review five cases previously described in the literature.
