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.

Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma , lymphangioma , ocular surface squamous neoplasia (OSSN), or amelanotic melanoma .
Peripheral odontogenic fibroma (PFO) is a fibrous connective tissue mass that is exophytic and covered in surface epithelium that contains odontogenic epithelium. [1] The World Health Organization (WHO) classifies peripheral odontogenic fibroma as a fibroblastic neoplasm with variable amounts of odontogenic epithelium that appears to be dormant.
A myxoid tumor is a connective tissue tumor with a "myxoid" background, composed of clear, mucoid substance. [1]Atrial myxoma. This tumoral phenotype is shared by many tumoral entities:
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 ...
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 ...
Odontogenic tumours are uncommon, with a prevalence of around 2% [9] and only 1-2% of these are ameloblastic fibromas. [5] As they are rare, there is limited evidence available, mostly case studies. There is a slight male predilection, developing most commonly within the first two decades of life.
