Calcifying epithelial odontogenic tumor VS calcifying odontogenic cyst

Calcifying epithelial odontogenic tumor, also known as Pindborg tumor, is a rare, benign, locally aggressive tumor that occurs in the same age range and in the same jaw sites as ameloblastoma. There is no gender predilection. A propensity for the mandibular molar region versus the premolar maxilla has been reported A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw.

Calcifying Epithelial Odontogenic Tumor - an overview

v. CALCIFYING ODONTOGENIC (EPITHELIAL) CYST - GORLIN The calcifying odontogenic cyst has many features of an odontogenic cyst and tumor - epithelial proliferation and continuous growth. It originates from developmental odontogenic epithelial tissue. The lesion usually occurs as a slowly enlarging, frequently painless and non-tender swelling of th The calcifying epithelial odontogenic tumor (CEOT) is a rare benign epithelial odontogenic neoplasm of slow growth that is locally aggressive and tends to invade bone and adjacent soft tissue. Here is reported the case of a 21-year-old female patient with a CEOT in the left mandibular posterior region. The computerized tomography in coronal plane revealed a hypodense lesion in the posterior. Calcifying epithelial odontogenic tumor, another locally aggressive, expansile tumor that may be heavily calcified, can strongly resemble an odontogenic myxoma at imaging. Treatment is surgical resection with a wide margin of bone because of the tendency of the tumor to infiltrate and recur ( , 1 ) The calcifying epithelial odontogenic cyst (CEOC) is a developmental odontogenic cyst, which was first categorized as a distinct entity by. Gorlin in 1962. It is an unusual and unique lesion. Odontogenic, neoplastic cysts: calcifying odontogenic cyst, carcinoma ex-cyst, keratocystic odontogenic tumor (often referred to as odontogenic keratocyst), unicystic ameloblastoma Non-odontogenic cysts: dermoid cyst , epidermoid cyst , median palatal cyst, nasopalatine duct cyst, surgical ciliated cyst

Table Calcifying cystic odontogenic tumor (CCOT), as defined by WHO, is a benign cystic neoplasm of odontogenic origin, characterized by an ameloblastoma-like epithelium with ghost cells that may calcify.1 The structure was first described by Gorlin et al in 1962 and was therefore called Gorlin cyst

Jaw tumors and cysts are relatively rare growths or lesions that develop in the jawbone or the soft tissues in the mouth and face. Jaw tumors and cysts, sometimes called odontogenic tumors and cysts, can vary greatly in size and severity. These growths are usually noncancerous (benign), but they can be aggressive and invade the surrounding bone. The calcifying epithelial odontogenic tumor is a benign odontogenic tumor of epithelial origin that accounts for approximately 1% of all odontogenic tumors. The origin of this neoplasm is not clearly known, although it is generally accepted to be derived from oral epithelium, reduced enamel epithelium, stratum intermedium or dental lamina remnants

It is a developmental odontogenic cyst, and its occurrence constitutes about 0.3-0.8% of all odontogenic cysts. Calcifying epithelial odontogenic cyst's are thought to be a unicystic process, which develop from the reduced enamel epithelium or remnants of odontogenic epithelium in the follicle, gingival tissue or bone Calcifying odontogenic cyst - A review. Calcifying odontogenic cyst (COC), also known as Gorlin cyst, is a rare developmental odontogenic lesion, introduced by Gorlin in 1962. COC exists either as a cystic or a solid variant. This lesion has been known by different names and classified into various subtypes True bone cysts are often encountered in facial bones due to the presence of embryonic epithelial rests in these bones. A majority of them are remnants of odontogenic apparatus.

INTRODUCTION The calcifying cystic odontogenic tumor (CCOT) is a rare lesion that represents less than 2% of all cysts and odontogenic tumors 1,2.There is still discussion in the literature regarding its nomenclature: some authors argue that this lesion does not present itself as a neoplasia with potential growth; however, other authors consider this lesion a tumor with cystic formations, with. The differential diagnosis of an expansile lesion in the maxillary sinus includes mucocele, fibrous dysplasia, hemangiopericytoma, dentigerous cyst, ameloblastoma, and Pindborg tumor. 2-4 The latter 3 lesions are of odontogenic origin and are commonly associated with impacted or unerupted teeth. The mucocele is the most common expansile mass in the maxillary sinus and results from obstruction.

Odontogenic cysts are common lesions with different biological behavior. Odontogenic keratocysts (OKCs) and calcifying odontogenic cysts (COCs) with ameloblastoma-like epithelium are more aggressive than dentigerous cysts (DCs) and radicular cysts (RCs). Therefore, they were included in the list of odontogenic tumors by WHO Commentary. Adenomatoid odontogenic tumor (AOT) is a rare tumor of epithelial origin accounting for between 2.2 and 7.1% of all odontogenic tumors and is given a ranking of fourth or fifth among the odontogenic tumors only surpassed by odontomas, myxomas, ameloblastomas and cemento-osseous tumors or lesions [1, 5].More than 95% of AOTs are intraosseous, but extraosseous variants have been.

Cementifying fibroma is considered as a benign, osseous tumour, which arises from the periodontal ligament and is composed of varying amounts of cementum, bone and fibrous tissue. It is very closely related to other fibro-osseous lesions like fibrous dysplasia, cemental periapical dysplasia and other calcifying odontogenic cysts and tumour. We report a case of this entity along with. INTRODUCTION The latest WHO classification of odontogenic tumors defines AOT as being a proliferation of odontogenic epithelium exhibiting a variety of histoarchitectural patterns embedded in mature connective tissue stroma characterized by slow and non-invasive growth 1.On the other hand, calcifying epithelial odontogenic tumor (CEOT) has been defined as a locally invasive epithelial neoplasm.
