Multiple fibromyxomas of the jaws: A case report

Abstract

Fibromyxoma is a synonym for odontogenic myxoma as reported in the World Health Organization (WHO) Classification 2005. It is a rare, benign, and locally aggressive odontogenic tumor of a mesenchymal origin, 1,2 comprising 3-6% of all odontogenic tumors. ] The mandible is more commonly affected than the maxilla, mainly in the posterior region. Usually, it causes a painless, slow-growing swelling. adiographically, it has been demonstrated as a unilocular or a multilocular radiolucency in the tooth-bearing area with a well-defined border, but sometimes, it does not match this definition. Root resorption is rarely found in cases of fibromyxoma, and the scalloping margin between the roots occurs more frequently. Maxillary lesions may cause invagination of the maxillary sinus and expansion of its walls as revealed in cross-sectional imaging modalities such as computed tomography. stologically, the tumor is composed of stellate and spindle-shaped cells with a haphazard arrangement in a loose mucinous or myxoid stroma, and its connective tissue may contain few collagen fibrils. Remnants of the odontogenic epithelium may also be present. his report describes a rare case of multiple fibromyxomas and highlights their clinical and radiographic features, including panoramic and magnetic resonance images, as well as histopathological features.
