Odontogenic Keratocyst Mandible An Interesting Case report and Literature review

The term odontogenic keratocyst was first described by Philipsen in 1956. This cyst actually arises
from the cell rests of dental lamina. It can occur anywhere in the jaw but is commonly seen in the
posterior part of the mandible. Since the clinical features and radiological appearance are not
characteristic this condition is commonly misdiagnosed. This is more so when the lesion is related to the nonvital tooth.
Odontogenic keratocyst has been rechristened as keratocystic odontogenic tumor by WHO working
group in 2005. This was necessitated to differentiate this lesion from its orthokeratinizing variant
which is currently considered as odontogenic cyst. This case report discusses odontogenic keratocyst
of mandible.
