Case Discussion

Odontogenic keratocyts are benign locally aggressive tumors. Odontogenic keratocytes are most of the time unilocular. They are often times associated with impacted tooth. They usually do not show tooth resorption. It is very important to differentiate from ameloblastoma which has more aggressive features; multicystic with solid enhancing components, strongly enhancing thick wall, bone and tooth resorption.
