Abstract

The latest (4th) edition of World Health Organisation of head and neck tumors has made number of significant changes. This review summarises changes in odontogenic and maxillofacial tumors by reintroducing a chapter on odontogenic cysts.

This edition restores the odontogenic keratocystic tumors as odontogenic keratocyst based on lack of evidence suggestion as true neoplasm.

This paper presents one of a case reports from the series thirty-two cases treated successfully with enucleation.

Introduction

The latest 4th edition of the world Health Organization classification of Head and Neck tumours has recently been published with a number of significant changes [1-4].

The most discussed change is reintroduction of the subtitle “odontogenic cysts” in the classification. The previous classification (2005), excluded any nontumorous lesions such as odontogenic and non-odontogenic cysts [4]. Hence, odontogenic keratocysts were classified as odontogenic keratocystic tumors. The decision of the recent reclassification of odontogenic cysts as odontogenic keratocyst was based on lack of evidence supporting its neoplastic potential.

We present one of the thirty-two cases of odontogenic keratocyst successfully treated with simple enucleation. This supports the view of present classification on odontogenic keratocyst as cystic lesion not tumors [1].

Case Report
