Calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare odontogenic epithelial neoplasm. So far, nearly 200 cases have been reported in the literature. We are reporting a case of CEOT in a 42-year-old male patient with painless bony swelling in the mandible.

What is driven snow appearance?

The tumor is frequently associated with an impacted molar (usually mandibular molar). The appearance of calcified streaks emanating from a central radio-opaque lesion has been likened to a driven-snow pattern. This panoramic radiograph is from the same case as the previous three images.

What is an odontogenic Tumour?

Odontogenic tumors are a heterogeneous group of lesions of diverse clinical behavior and histopathologic types, ranging from hamartomatous lesions to malignancy. Because odontogenic tumors arise from the tissues which make our teeth, they are unique to the jaws, and by extension almost unique to dentistry.

What is AOT in dentistry?

Abstract. Adenomatoid odontogenic tumor (AOT) is a well-recognised slow growing benign tumor derived from complex system of dental lamina or its remnants. This lesion is categorised into three variants of which the more common variant is follicular type which is often mistaken for dentigerous cyst.

What is Pindborg?

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.

What is an odontogenic fibroma?

Central odontogenic fibroma (COF) is an extremely rare benign tumor that accounts for 0.1% of all odontogenic tumors. It appears as an asymptomatic expansion of the cortical plate of the mandible or maxilla. Radiologically it presents as a unilocular or multilocular radiolucency.

What does white as the driven snow mean?

Adjective. white as driven snow (not comparable) (simile) extremely white; totally white (of a color).

What is odontogenic myxoma?

Odontogenic myxoma is a rare intraosseous neoplasm, which is benign but locally aggressive. It rarely appears in any bone other than the jaws. It is considered to be derived from the mesenchymal portion of the tooth germ.

What does as pure as driven snow mean?

Morally unsullied, chaste, as in She’s just sixteen and pure as the driven snow. This simile dates from the late 1500s, although driven, which means “carried by the wind into drifts,” was occasionally omitted.

How common are odontogenic tumors?

Individually, of all odontogenic tumors, 75.9% were odontomas. The prevalence of the remaining tumors appears to be a rare occurrence. The second most common was ameloblastoma (11.7%), followed by odontogenic myxoma (2.2%). Odontomas are considered hamartomas or developmental anomalies.

What does odontogenic mean?

Medical Definition of odontogenic 1 : forming or capable of forming teeth odontogenic tissues. 2 : containing or arising from odontogenic tissues odontogenic tumors.

WHO classification benign odontogenic tumors?

BENIGN ODONTOGENIC TUMORS, EPITHELIAL Ameloblastomas were classified as solid/multicystic, extraosseous/peripheral, desmoplastic, and unicystic types in the 2005 classification. The 2017 classification has been narrowed to ameloblastoma, unicystic ameloblastoma, and extraosseous/peripheral types.

How can you tell the difference between AOT and Dentigerous cysts?

The characteristic radiographic difference between dentigerous cyst and follicular AOT is that the radiolucency in the former is never associated with part of the root (always attached at the cervix) whereas in the latter it is most commonly associated with the part of the root.

How is Adenomatoid odontogenic tumor treated?

Adenomatoid odontogenic tumor is a rare benign epithelial odontogenic tumor that can be treated by local excision. Expert morphological diagnosis is required to establish differential diagnosis, in particular from ameloblastoma, thus preventing extensive surgery.

What is odontogenic cyst?

Odontogenic cysts are epithelial-lined pathologic cavities and surrounded by fibrous connective tissue that originate from odontogenic tissues that occur in tooth-bearing regions of maxilla and mandible. Cystic conditions of the jaw cause bony destruction and may cause resorption or displacement of adjacent teeth.

What is Cementoblastoma?

Abstract. Benign cementoblastoma is a rare odontogenic tumor characterized by the formation of a mass of cementum or cementum-like tissue attached to the roots of a tooth. Cementoblastoma are distinctive but relatively uncommon tumors.

What is Ameloblastic fibroma?

Ameloblastic fibroma (AF) is an extremely rare true mixed benign tumor that can occur either in the mandible or maxilla.[1] It is frequently found in the posterior region of the mandible, often associated with an unerupted tooth.[2] It usually occurs in the first two decades of life with a slight female predilection, …

What is primordial cyst?

A primordial cyst is a developmental odontogenic cyst. It is found in an area where a tooth should have formed but is missing. Primordial cysts most commonly arise in the area of mandibular third molars.

What causes odontogenic fibroma?

Odontogenic fibroma (OF), a rare odontogenic tumor of mesodermal origin, has been thought to originate from either dental follicle, periodontal ligament, or dental papilla [1]. Different studies reported high variability in the incidence rate as being between 3 and 23% of all odontogenic tumors [2,3].

Is fibroma malignant?

They can grow in all organs, arising from mesenchyme tissue. The term fibroblastic or fibromatous is used to describe tumors of the fibrous connective tissue. When the term fibroma is used without modifier, it is usually considered benign, with the term fibrosarcoma reserved for malignant tumors.

What is giant cell fibroma?

Giant cell fibroma is a form of fibrous tumour affecting the oral mucosa. Its occurrence is relatively rare in paediatric patients. Clinically it is presented as a painless, sessile, or pedunculated growth which is usually confused with other fibrous lesions like irritation fibromas.

Who said pure as the driven snow?

The phrase “as pure as the driven snow” seems to have been used by William Shakespeare for the first time in his play, The Winter’s Tale, where Autolycus used it as “Lawn as white as driven snow” and in Macbeth where Malcolm has used it referring to Macbeth that he “will seem as pure as snow.” Since then, it has become …

Is Odontogenic myxoma painful?

Just as it happens to most odontogenic tumors, the odontogenic myxomas are asymptomatic, causing pain, paresthesia or asymmetries only when they take on larger sizes. Their growth is usually slow, however they are locally aggressive.

Is myxoma cancerous?

A myxoma is a benign (non-cancerous) growth in the heart.

Are myxoma tumors odontogenic?

The odontogenic myxoma is an uncommon benign odontogenic tumor arising from embryonic connective tissue associated with tooth formation. As a myxoma, this tumor consists mainly of spindle shaped cells and scattered collagen fibers distributed through a loose, mucoid material.

Is pure as the driven snow a cliche?
