Introduction: The odontogenic myxoma is generally considered to be a rare neoplasm unique to the jaws. In the international histological classification of odontogenic tumors, odontogenic myxoma (OM) is defined as a benign odontogenic tumor of mesenchymal origin that is locally invasive and consists of rounded and angular cells lying in abundant mucoid stroma. Since these neoplasms are rare in t...

The primary aim of this paper is to present clinical and radiographic aspects of odontogenic myxomas diagnosed at the Stomatology Clinic of Bauru School of Dentistry, University of São Paulo, Brazil and to compare them with data reported in a series published in the literature. A second objective is to report a clinical case of odontogenic myxoma in a 9-year-old patient in whom the lesion invol...

Background. The aim of this study was to investigate myofibroblast (MF) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of MFs and the clinical behavior of these lesions. Methods. A total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (UAM), solid ameloblastoma (SA), odontogenic keratocyst (OKC), dentigerous cyst (DC), rad...

In this study, we compared mast cell tryptase and CD31 expression between odontogenic tumors with the aim of predicting the clinical behavior of these lesions at the time of initial biopsy. We also evaluated the correlation between mast cell tryptase and CD31 expression to clarify the role of mast cells (MCs) in the growth of odontogenic tumors. Immunohistochemical staining with anti-MC tryptas...

Odontogenic myxoma (OM) is a mesenchymal tissue benign neoplasia, being relatively rare which is almost exclusively seen in tooth-bearing areas. OM commonly occurs in the 2(nd) and 3(rd) decade and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. Radiographically, the myxoma appears as a unilocular or multilocu...

Myxomas of the jaws are believed to arise from odontogenic ectomesenchyme. They bear a close resemblance to the mesenchymal portion of a developing tooth. Myxomas are predominantly found in young adults. Radiographically myxomas appear as unilocular or multilocular radiolucencies. The radiolucent defect can contain thin, wispy trabeculae of residual bone which are often arranged at right angles...
