Keratocystic odontogenic tumor involving the maxillary antrum with displacement of the third molar: A rare case report

Abstract

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw with a high rate of recurrence. The lesion commonly occurs in the mandibular molar-ramus area and is rarely seen in the maxilla. Its occurrence in the maxillary sinus along with a displaced third molar is very rare. This article reports a case of KCOT in a 15-year-old boy with a displaced third molar involving the right maxillary antrum.
