Peripheral
odontogenic myxoma: A review of the literature and report of two cases.
Odontogenic myxoma: case report with reconstructive considerations.
The radiographic feature of the present case was well-defined, multilocular radiolucency with several straight septa that resembled
odontogenic myxoma.
This is different for ameloblastoma,
odontogenic myxoma or central giant cell lesion--most likely they show cortical rupture and are sensitive to palpation.
Odontogenic myxomas are rare, benign neoplasms apparently arising from the mesenchymal portion of the tooth-forming unit known as the dental papillae/dental sac.
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 differential diagnosis of a POF includes a fibrous epulis and odontogenic gingival epithelial hamartoma, whereas for a COF one needs to consider hyperplastic dental follicles, myxofibroma, desmoplastic fibroma,
odontogenic myxoma, intraosseous neurofibroma, and possibly carcinoma.
The radiographic differential diagnosis included
odontogenic myxoma, desmoplastic fibroma, and myofibromatosis.
It includes ameloblastoma,
odontogenic myxoma, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor (Pindborg tumor), calcifying odontogenic cyst (Gorlin cyst), ameloblastic fibroma, ameloblastic fibro-odontoma, compound odontoma, and complex odontoma.
Histologic examination identified the mass as an
odontogenic myxoma. Clinically, the patient remained asymptomatic after 2 years.
