Dental Radiography and Imaging

Calcifying epithelial odontogenic tumor (CEOT) (Pindborg's tumor) is a benign odontogenic neoplasm that comprises about 1% of all odontogenic tumors and presents locally aggressive biological behavior. CEOT affects patients in a broad age range and it is usually found on the posterior mandible. Caucasian man, 19, presented swelling in the region of the right maxilla present for 6 months. Imaging showed the presence of an extensive radiolucent lesion associated with the second and third unerupted molars. Needle aspiration was performed, and a white liquid was obtained. An incisional biopsy was done. Histopathological analysis found polyhedral epithelial cells with distinct contours, hyperchromatic nucleus, amyloid-like material, and basophilic calcified material, establishing the diagnosis of CEOT. Marsupialization was performed. No significant changes have been seen during close follow-up. The overall prognosis is good.
