title: Keratocystic odontogenic tumor with impacted maxillary third molar involving the right maxillary antrum: an unusual case report.
abstract: The odontogenic keratocyst (OKC), first described by Phillipsen in 1956, has metamorphosized as a keratocystic odontogenic tumor (KCOT) as reported in WHO classification of head and neck tumors in 2005. KCOT is a benign intraosseous neoplasm of the jaw and its occurrence in maxilla is unusual and its appearance in maxillary antrum along with maxillary impacted third molar is very uncommon. This article reports a case of KCOT associated with impacted maxillary third molar in right maxillary antrum and describes its rare site of occurrence.
