title: [Morphologic and differential diagnosis of sclerosing perineurioma].
abstract: The paper discusses morphologic and immunohistochemical characteristics of sclerosing perineurioma. Generally, it is well circumscribed and consists of tiny spindle-shaped plump epitheloid cells embedded in collagenous hyalinized matrix. Immunohistochemically, it was represented by EMA+, S-100, AE1/AE3, CAM 5.2, smooth muscle actin and desmin. Being benign, tumor was identified by differential diagnosis using fibroma of tendon sheath, sclerosing one, glomal tumor, giant cell tumor and sclerosing epitheloid cell sarcoma.
