The odontogenic myxoma is an uncommon benign odontogenic tumor arising from embryonic connective tissue associated with tooth formation. [1] As a myxoma , this tumor consists mainly of spindle shaped cells and scattered collagen fibers distributed through a loose, mucoid material.
An odontogenic tumor is a neoplasm of the cells or tissues that initiate odontogenic processes. Examples include: Adenomatoid odontogenic tumor; Ameloblastic fibroma; Ameloblastic fibro-odontoma; Ameloblastoma, a type of odontogenic tumor involving ameloblasts; Ameloblastic fibrosarcoma; Calcifying cystic odontogenic tumor; Calcifying ...
Ameloblastoma is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. [1] It was recognized in 1827 by Cusack. [2]
The Ameloblastic Fibroma epithelial tissue could be confused with the most common odontogenic tumour, the Ameloblastoma. Therefore the mesenchymal component is histologically important in differential diagnosis. [7] The mesenchymal stroma in normal development is a rich myxoid connective tissue.
Odontomas are thought to be the second most frequent type of odontogenic tumor worldwide (after ameloblastoma), accounting for about 20% of all cases within this relatively uncommon tumor category which shows large geographic variations in incidence. According to the same article discussion, statistics might appear misleading as most of the ...
The odontogenic epithelium may be either arranged as follicles that resemble developing enamel organ or they may be seen as cords or strands. The peripheral cells of the follicles resemble ameloblast like cells The odontogenic epithelium is scattered in a loose connective tissue stroma that closely resembles dental papilla .
The calcifying epithelial odontogenic tumor (CEOT), also known as a Pindborg tumor, is an odontogenic tumor first recognized by the Danish pathologist Jens Jørgen Pindborg in 1955. [1] It was previously described as an adenoid adamantoblastoma , unusual ameloblastoma and a cystic odontoma . [ 1 ]
