CALCIFYING EPITHELIAL ODONTOGENIC-TUMOR (PINDBORG TUMOR) - REPORT OF CASE

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic lesion that comprises from 0.2% to 1% of all odontogenic tumors.1 Clinically in manifests as a bony lesion, accounting for the majority of cases (95%), or as the extremely rare peripheral type (5%). In the past a number of different names have been given to this lesion, such as calcifying ameloblastoma,1 malignant odontoma,1 adamantoblastoma,2 adenoid adamantoblastoma,3 cystic complex odontoma,3 uncommon ameloblastoma with calcifications,1 and others. In 1956, Pindborg4 delineated this lesion as a distinct entity and named it the calcifying epithelial odontogenic tumor. In 1963, along with a comprehensive review of the literature, Shafer et al5 suggested the eponym "Pindborg tumor.". The purpose of this article is to report an additional case of the CEOT and discuss important aspects of the radiographic appearance, histologic features, clinical behavior, and surgical management. © 1992.
