title: Calcifying epithelial odontogenic tumor (Pindborg tumor) without calcification: A rare entity.
abstract: The calcifying epithelial odontogenic tumor is a rare benign odontogenic tumor that was first described by Pindborg in 1955. It accounts for less than 1% of all odontogenic neoplasms. The tumor is characterized histologically by the presence of polygonal epithelial cells, calcification, and eosinophilic deposits resembling amyloid. Noncalcifying Pindborg tumor is very rare and only three cases have been documented in the English language literature so far. We present an additional case of noncalcifying Pindborg tumor and review the previously reported cases. Because noncalcifying Pindborg tumor is believed to be an aggressive variant, a definitive resection of the tumor with tumor-free surgical margins and long-term follow-up is recommended.
