What is odontogenic myxoma?

What is odontogenic myxoma?

Odontogenic myxoma is a rare benign tumour of the jaw and characteristically presents as a slow, painless, bony expansion with resultant facial deformity. It is most commonly associated with an unerupted tooth and probably arises from the mesenchymal portion of the tooth germ [1]. According to a study by Regezi et al.

Is Odontogenic myxoma painful?

Odontogenic myxoma (OM) is a rare benign painless, slow-growing lesion with local aggressive behavior. Pain and sensory disturbance and fibro-osseous appearance in histopathology have been rarely reported in OM.

What is the treatment of odontogenic myxoma?

Histopathologically, OMs are characterized by spindle-, wedge-, or stellate-shaped cells loosely arranged in an abundant mucoid background. Myxomas are mainly asymptomatic. Radical surgery, excision, and enucleation followed by curettage of the surrounding bony tissue have all been advocated as treatment options.

Is Odontogenic myxoma benign or malignant?

Odontogenic myxoma is a benign but invasive tumor that has a high rate of recurrence after surgical removal (Speight, 2013).

What is a myxoma?

A myxoma is a primary heart (cardiac) tumor. This means that the tumor started within the heart. Most heart tumors start somewhere else. Primary cardiac tumors such as myxomas are rare. About 75% of myxomas occur in the left atrium of the heart.

Does odontogenic myxoma cause root resorption?

[15] However, the classical radiographic features of the odontogenic myxoma, where the bony trabeculae of a multilocular radiolucency intersect at right angles and the lesion causes root resorption, resulting in tooth mobility,[2,5,10] were readily identifiable in our case.

How common is odontogenic myxoma?

Odontogenic myxomas are rare benign neoplasm of mesenchymal origin, comprising 3–6% of all odontogenic tumors.

What is an odontogenic fibroma?

Abstract. 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 a myxoma look like?

An Atrial Myxoma can be polypoid, round, or oval in shape. They have a gelatinous consistency. They often present with a smooth or lumpy surface and are usually white, yellowish, or reddish.

What is the most common odontogenic tumor?

Odontoma. This benign tumor is the most common odontogenic tumor. Odontomas often have no symptoms, but they may interfere with tooth development or eruption. Odontomas are made up of dental tissue that grows around a tooth in the jaw.

What causes odontogenic fibroma?

Peripheral odontogenic fibroma (formerly known as fibromatous and ossifying epulis) is a benign, often slow-growing tumor that arises from periodontal structures (gums, ligaments, and bone).

What causes a myxoma?

Atrial myxomas are sometimes linked with valve obstruction stenosis and atrial fibrillation. Myxomas are more common in women. About 1 in 10 myxomas are passed down through families (inherited). These tumors are called familial myxomas.

WHO classification odontogenic Tumours?

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.

What is the difference between cyst and tumor?

A cyst is a sac or capsule that’s filled with tissue, fluid, air, or other material. A tumor is usually a solid mass of tissue.
