title: [Perineuriomas and other tumors with perineurial differentiation].
abstract: This is a review of the literature on the peripheral nerve sheath tumors with perineural differentiation. The authors provide an overview of the clinicopathological, immunohistochemical, ultrastructural, and genetic features of these neoplasms. Emphasis is laid on various morphological variants of perineurioma (intraneural, retifrm, sclerosing, plexiform, atypical, malignant, etc.) and so-called hybrid tumors (schwannoma-perineurioma, neurofibroma-perineurioma).
