Aggressive calcifying epithelial odontogenic tumor masquerading as maxillary sinus tumor: a case report.

Abstract

Calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. Its occurrence in the maxillary sinus is very rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures. We report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. The purpose of this article is to report an additional case of calcifying epithelial odontogenic tumor and discuss the radiologic appearance, histologic features, and to highlight its clinical behavior.
