An unusually extensive orthokeratinized odontogenic cyst: A case report

Abstract

While odontogenic keratocysts (OKC) are fairly common and well-known, orthokeratinized odontogenic cysts (OOCs) are quite rare accounting for less than 1% of odontogenic cysts. The entity is characterized by the presence of a predominant orthokeratinized lining. OOC is much less aggressive as compared to OKC and simple enucleation is discerned as adequate treatment with minimal chances of recurrence. The present case report describes an extensive OOC that involved most of the angle and ramus of the mandible in a 25-year-old female.
