title: Benign nerve sheath myxoma: light and electron microscopic features of two cases.
abstract: Two new cases of the rare benign nerve sheath myxoma (NSM) are presented. The light microscopic findings are compared with previously reported cases. In addition, the ultrastructural features of three constitutent cell types are described. The lesion is confirmed as a neural sheath neoplasm, and its similarities to other myxomas are discussed.
