Intraosseous Calcifying Epithelial Odontogenic (Pindborg) Tumor: A Rare Entity

Abstract

Calcifying epithelial odontogenic tumor (CEOT) is a locally aggressive, rare benign odontogenic neoplasm that accounts for <1% of all odontogenic tumors. It was first described by a Dutch pathologist Jens Jorgen Pindborg in 1955. It is most often located in the posterior mandible. The tumor usually appears between the second and sixth decade of life and has no gender predilection. It is slow‑growing neoplasm with a recurrence rate of 10–15% and with rare malignant transformation. Early diagnosis is essential to avoid oro‑maxillofacial deformation and destruction. CEOT is rarely reported in India. We, herewith present a rare case of CEOT with unusual features associated with an impacted right third molar in the posterior mandible of 35 years male, with an emphasis on clinical, radiographic, histopathology and immunohistochemical features.
