keratocyst

ker·a·to·cyst

(ker'ă-tō-sist),
Odontogenic cyst derived from remnants of the dental lamina and appearing as a unilocular or multilocular radiolucency that may produce jaw expansion; epithelial lining is characterized microscopically by a uniform thickness, a corrugated superficial layer of parakeratin, and a prominent basal layer composed of palisaded columnar cells; associated with the bifid rib basal cell nevus syndrome.

keratocyst

/ker·a·to·cyst/ (ker´ah-to-sist) an odontogenic cyst lined with a layer of keratinized squamous epithelium and commonly associated with a primordial cyst.

keratocyst

[ker′ətōsist′]
a thin-walled, tooth-forming cyst lined by keratinizing epithelium. It may be solitary or part of a multiple lesion, most frequently in the posterior body or ramus of the mandible, and may or may not be associated with teeth.

Odontogenic keratocyst, in cysts of the oral and maxillofacial regions.
Differential diagnosis like ameloblastoma, ameloblastic fibroma, odontogenic fibroma, central hemangioma, or odontogenic keratocyst along with OM could be listed as initial diagnostic hypothesis based on the clinical and radiological findings.
Results: Out of total 100 patients, 58% were diagnosed with radicular cysts, 25% with dentigerous cysts, 15% with odontogenic keratocyst, 1% patient with calcifying epithelial odontogenic cyst and 1% patient was diagnosed with eruption cyst.
1) In 2005, the World Health Organization (WHO) classified odontogenic keratocyst (OKC) as a keratocystic odontogenic tumor (KCOT).
Owing to its specific histopathological features, aggressive behavior and high recurrence rates, the odontogenic keratocyst was reclassified and renamed "keratocystic odontogenic tumor" (KCOT) in the World Health Organization (WHO) classification of head and neck tumors in 2005.
For the multilocular lesions in the mandible ramus, differential diagnoses of SBC were: ameloblastoma, odontogenic keratocyst, odontogenic myxoma, and central giant cell lesion.
16) They can mimic ameloblastoma, keratocyst and fibro-osseous lesions such as fibrous dysplasia when they have honeycomb or soap-bubble appearances (17) (Figure 15).
INTRODUCTION: Resection of the mandible and immediate reconstruction with autogenous bone graft are widely used in the treatment of odontogenic keratocyst involving a large section of the mandible.
DCs are the third most common odontogenic cysts, after radicular cysts and odontogenic keratocyst, and account for approximately 10.
Previous studies have suggested that the lining of a keratocyst is only 5 or 6 cells thick and tears easily during enucleation, in turn, causing a high recurrence rate.
