title: [Myxoma of the nerve sheath. Apropos of a case].
abstract: A case of oral nerve sheath myxoma is presented with the findings of light microscopy and immunochemistry. The tumor consists of well-defined lobules which are separated by septa composed of fibrous connective tissue that reassembled the perineurium. Each lobule is composed of elongated and stellate cells in a basophilic mucoid matrix. Immunohistochemically, S-100 protein is strongly positive in all tumor cells. The histogenesis and differential diagnosis are discussed.
