Peripheral Odontogenic Keratocyst of Buccal Mucosa

The odontogenic keratocyst is a developmental cystic lesion of jaw bones.There is an on-going debate about the pathogenesis of this entity.Odontogenic keratocysts are usually seen intraosseously in jaws with a predilection in the mandibular molar ramus regions.Extra-skeletal variants are reported rarely in the gingiva.Extra-skeletal variants occurring peripherally in other soft tissue components of the oral cavity are extremely rare.Even though histogenesis is ambiguous, such presentation may be related to the tumour-like behaviour of odontogenic keratocysts.Here, we present a case of peripheral odontogenic keratocyst in a 62-year male who presented with complaint of a painless lump on the right buccal mucosa.The diagnosis was made on biopsy of the lesion.The lesion was excised completely.
