title: [Tumors of the choroid plexus: morphologic and immunohistochemical study].
abstract: We present a morphological and immunohistochemical study on three papillomas and one carcinoma of the choroid plexus. Clinical characteristics are analysed. Morphological criteria for malignancy are: solid histological pattern, cellular polymorphism, nuclear atypia and infiltration of nervous tissue. The immunohistochemical study shows the value of GFAP, S-100 protein, HNK-1 and Vimentin as specific markers. In the discussion we point out the differential diagnosis between these types of tumors and the metastasis from papillary carcinomas and ependymomas.
