Odontogenic keratocyst (OKC) was first introduced by Phillipsen in 1956 to describe keratin containing jaw cysts. This cyst is considered unique because of its aggressive behavior, high recurrence rate, and characterstic histopathologic features. In 2005, the World Health Organization reclassified OKC and named it as "keratocystic odontogenic tumor" (KCOT). It frequently involves the mandibular posterior region and involvement of the posterior maxilla is a rare occurrence. However, when it does, it can easily expand to occupy the entire maxilla. Hence, this article highlights this rarity by reporting a case of OKC associated with impacted right maxillary third molar in the maxillary antrum.
