Calcifying Epithelial Odontogenic Tumor Without Calcification: A Rare Entity

Abstract

Pindborg in 1955, for the first time described four cases of a rare benign odontogenic tumor. Shafer et al called this entity Pindborg tumor. This was later referred to as the calcifying epithelial odontogenic tumor. It accounts for less than 1% of all odontogenic neoplasm. This tumor is characterized mainly by the presence calcification and eosinophilic deposits resembling amyloid including presence of polygonal epithelial cells. It is very rare to find non calcifying epithelial odontogenic tumor with only 5 cases documented till .Here we present another case of non-calcifying Pindborg tumor, which first came to the department as a follicular tissue and was histologically diagnosed as a calcifying epithelial odontogenictumor. It is considered that noncalcifying Pindborgtumor is an aggressive variant, hence a long term follow-up after surgery is recommended.
