Abstract

The calcifying epithelial odontogenic tumor (CEOT) is a rare and benign odontogenic epithelial neoplasm. This tumor accounts for less than 1% of all odontogenic tumors. It normally affects patients between 30 and 50 years old, and it is typically located in the posterior region of the mandible. Involvement of the maxillary sinus has previously been published only in six cases. This report presents a single case of CEOT that invades the maxillary sinus in a 69-year-old male. We performed a left partial maxillectomy and immediate reconstruction of the defect with a temporalis muscle flap. A comprehensive immunohistochemical study was reported. No recurrences have been found after 8 years of follow-up.
