In meningiomas, transformed meningeal cells can share morphological aspects (in hemangiopericytic meningioma) and antigenic properties (i.e.: HLA-DR antigens expression) with elements of the monocyte/macrophage lineage. In this report, we describe a case of a highly vascular meningioma where numerous tumor cells, studied with immunohistochemical methods, present phenotypic properties of macrophages. Moreover, the cerebrospinal fluid (CF) analysis disclosed, using a biological assay, a high level of a growth factor for monocytic elements, the Macrophages Colony Stimulating Factor (M-CSF). Our findings may confirm that transitional aspects between different mesenchymal cells could be present in meningiomas.

Abstract
In meningiomas, transformed meningeal cells can share morphological aspects (in hemangiopericytic meningioma) and antigenic properties (i.e.: HLA-DR antigens expression) with elements of the monocyte/macrophage lineage. In this report, we describe a case of a highly vascular meningioma where numerous tumor cells, studied with immunohistochemical methods, present phenotypic properties of macrophages. Moreover, the cerebrospinal fluid (CF) analysis disclosed, using a biological assay, a high level of a growth factor for monocytic elements, the Macrophages Colony Stimulating Factor (M-CSF). Our findings may confirm that transitional aspects between different mesenchymal cells could be present in meningiomas.Pubblicazioni consigliate
