Abstract

Calcifying epithelial odontogenic tumor, also known as Pindborg tumor, is a rare benign odontogenic tumor. This tumor predominantly involves the mandible, though the maxilla can also be involved in some cases. The involvement of maxillary sinuses, however, has been previously reported in only 8 case reports English literature. These patients chiefly presented with nasal obstruction along with epistaxis or proptosis in rare cases. However, a primary presentation as nasal polyp is unheard of. We present a rare case of calcifying epithelial odontogenic tumor presenting as a nasal polyp, posing a diagnostic difficulty.
