o·don·to·gen·ic myx·o·ma

a benign, expansile, multilocular radiolucent neoplasm of the jaws consisting of myxomatous fibrous connective tissue; presumably derived from the mesenchymal components of the odontogenic apparatus.

odontogenic myxoma

a rare tumor of the jaw that may develop from the mesenchyme of the tooth germ.

odontogenic myxoma (ōdon´tōjen´ik miksō´mə),

n a deep lesion in a maxillary or mandibular tooth germ's mesenchyme. It occurs equally in males and females between the ages of 10 and 30. The tumor may displace teeth and spread to other locations.

However when the ameloblastoma shows a typical expansile multilocular aspect, the differential diagnosis can include a variety of odontogenic or non-odontogenic lesions with similar characteristics like odontogenic keratocysts, aneurysmal bone cysts, adenomatoid odontogenic tumors, odontogenic myxomas, and giant cell central lesions.
In odontogenic myxoma cases, intense reactivity to [alpha]SMA was detected in the population of stellate and spindle cells, in about 85% of the cells per high power field.
The selected tumors were four cases of follicular ameloblastomas (FA), four of ameloblastic fibro-odontomas (AFO), four of adenomatoid odontogenic tumors (AOT), four of calcifying epithelial odontogenic tumors (CEOT) and four of odontogenic myxomas (OM).
Expression of matrix metalloproteinases 2 and 9 in odontogenic myxoma in vivo and in vitro.
Odontogenic myxomas are rare benign tumors that can exert destructive effects in some cases.
The differentiation of POTs from odontogenic myxomas is mandatory, considering the fact that odontogenic myxomas are more aggressive tumors and require more aggressive mode of treatment.
They include 20 cases of Ameloblastoma, 5 calcifying epithelial odontogenic tumour, 10 adenomatoid odontogenic tumours, 10 ameloblastic fibromas and 10 cases of odontogenic myxomas.
Due to its nonexclusive histological features, this lesion is often confused with other entities, such as hyperplastic dental follicles, odontogenic myxomas, and desmoplastic fibromas, which highliaght the importance of clinical pathological correlation in the diagnosis of odontogenic fibromas.
