orthokeratinized odontogenic cyst

The orthokeratinized odontogenic cyst OOC is a rare developmental jaw cyst. The orthokeratinized odontogenic cyst may share some histologic features with OKC but is orthokeratinized not parakeratinized and lacks the palisaded basal cell layer.

Orthokeratinized odontogenic cyst OOC was first described by Schultz in 1927 and in 1945 Philipsen considered it to be a variant of Odontogenic keratocyst OKC.

. Orthokeratinized odontogenic cyst usually occurs most often between third and fourth and decades and with a male gender predilection. The treatment of OOC is by enucleation and the prognosis following enucleation is excellent with a recurrence rate of less than 2. In contrast to other studies the lesion was located in the body of mandible starting from lower left canine region involving lower left premolars and lower left first molar.

The databases searched were the PubMed interface of MEDLINE and LILACS. OOC should be histopathologically differentiated from OKC which has a higher recurrence rate and lower malignant potential. The aim of this study was to report a large series of OOC to substantiate its clinicopathologic profiles and to investigate PTCH1 mutations in OOCs.

Orthokeratinized odontogenic cyst OOC is a rare intraosseous cyst characterized by an orthokeratinized epithelial lining and minimal clinical aggressiveness. Orthokeratinized odontogenic cyst OOC a newly designated entity of odontogenic cysts is an intraosseous jaw cyst that is entirely or predominantly lined by orthokeratinized squamous epithelium. A calcified odontogenic cyst has basal palisading but has very distinctive ghost cells.

OOC exhibits distinctive clinical pathologic and behavioral features that varied substantially from KCOT and hence now it is considered as a separate entity. This 50-year-old female patient came for extraction of her right maxillary second molar with. Odontogenic cysts are closed sacs and have a distinct membrane derived from rests of odontogenic epithelium.

Orthokeratinized odontogenic cyst OOC is an odontogenic cyst was initially termed as the uncommon orthokeratinized type of odontogenic keratocyst by the World Health Organization. Orthokeratinized odontogenic cyst OOC is an uncommon odontogenic cyst. OOC had been previously coded as odontogenic keratocyst OKC and was termed as orthokeratinized variant of OKC.

In 2005 it was classified as a distinct entity. Only those reports of OOCs that occurred. 1 Here we reported an OOC that presented as a residual cyst at the right maxillary tuberosity in a 50-year-old female patient.

Orthokeratinized Odontogenic Cyst OOC is a rare developmental odontogenic cyst which was considered in the past to be a variant of Odontogenic keratocyst OKC later renamed as keratocystic odontogenic tumor KCOT. Recognition of OOC as a unique entity has long been due yet its inexplicable radiographic presentation resembling dentigerous cyst histological likeness to odontogenic keratocyst OKC and inconsistent cytokeratin expression profiles overlapping with both as well as with the. However they have been redefined as a distinct entity.

It usually occurs in mandible. Orthokeratinized odontogenic cyst OOC is a relatively rare odontogenic cyst characterized by the presence of orthokeratinized epithelial lining. It has been categorized as a subtype of odontogenic keratocyst OKC.

These cysts were originally classified as a subtype of odontogenic keratocysts. It may contain air fluids or semi-solid material. In this case 30-year-old female was reported with OOC.

Orthokeratinized Odontogenic Cyst OOC is a rare developmental odontogenic cyst which was considered in the past to be a variant of Odontogenic keratocyst OKC later renamed as keratocystic odontogenic tumor KCOT. The aims of the review were to evaluate the principal clinical and conventional radiographic features of orthokeratinized odontogenic cyst OOC by systematic review SR and to compare the frequency of OOC between four global groups. Orthokeratinized odontogenic cysts are a rare type of odontogenic cyst which are identified by an orthokeratinized stratified squamous epithelium.

Orthokeratinized odontogenic cyst OOC is a relatively uncommon developmental cyst comprising about 10 of cases that had been previously coded as odontogenic keratocysts OKCs16 In 1981 Wright2 reported 59 cases of what he then termed orthokeratinized variant of OKC which showed little clinical aggressiveness. The orthokeratinized odontogenic cyst OOC 1 was first clearly identified as an orthokeratinzed variant of the odontogenic keratocyst by Wright in 1981 2 owing to its different histopathology and reduced likelihood to recur. Intra-bony cysts are most common in the jaws because the mandible and maxilla are the only bones with.

Orthokeratinized odontogenic cyst OOC is a developmental cyst of odontogenic origin and was initially defined as the uncommon orthokeratinized variant of odontogenic keratocyst OKC. The treatment of OOC is by enucleation and the prognosis following enucleation is excellent with a. However there had been controversy because the histological and clinical features of OOC and.

Odontogenic cyst are a group of jaw cysts that are formed from tissues involved in odontogenesis. Orthokeratinized odontogenic cyst OOC is a rare developmental odontogenic cyst characterized by orthokeratinized stratified squamous epithelial lining. OOCs were first described in 1927 by Schultz 2 as a variant of odontogenic keratocysts now known as keratocystic odontogenic tumours KCOTs 3.
