Odontogenic keratocyst (OKC) is a cyst of dental origin with an aggressive clinical behavior, having high recurrence rate. Odontogenic keratocyst denoted as OKC is a rare and benign cystic lesion of the jaws accounting for 10-12 percent of all jaw cysts. It is of particular interest because of its high recurrence rate and aggressive nature. It can be uni- or multilocular, it has an invasive growth, and . Single OKC are very well documented. In the WHO/IARC classification of head and neck pathology, this clinical entity had been known for years as the odontogenic keratocyst; it was . Odontogenic keratocyst (OKC) is the cyst arising from the cell rests of dental lamina. Multiple odontogenic keratocysts (OKCs) are a well-recognized feature of NBCCS (see the image below). stratified epithelium with "ribbon-like appearance" with palisaded basal cell layer, parakeratosis, artefactual separation of epithelium from the basement membrane. 1 . Odontogenic cysts. Odontogenic keratocysts arise from rests of dental lamina and present most typically as a symptomless expansion of the jaw associated with a multilocular radiolucency. Clinically it is characterized by a high rate of recurrence after treatment and by the potential to become an aggressive, bone-destructive lesion. The angle of the mandible is the most common site. }, author={Mervyn Shear}, journal={Oral and maxillofacial surgery clinics of North America}, year={2003}, volume={15 3}, pages={ 335-45 } } M.

It can occur anywhere in the jaw, but commonly seen in the posterior part of the mandible. Clinical relevance: The volume reduction rate and pattern of decompression of the OKC can be predicted and clinicians should be considered when treating OKC via decompression. It is also known as a calcifying cystic odontogenic tumor, which is a proliferation of odontogenic epithelium and scattered nest of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. found in infancy to old age; 60% found between 10 and 40; male > female.
