Occasionally variants of meningeal hemangiopericytomas (HPC) may be confused with primary and secondary tumours of the meninges by virtue of their features and patterns of growth. Until now, a specific immunohistochemical marker for HPC could not be identified. HPC are reported to express factor XIIIa (F XIIIa) in the cytoplasm of the tumour cells. In an effort to assess the diagnostic value of F XIIIa for meningeal HPC, we investigated 38 primary meningeal tumours (6 HPC, 28 meningiomas of various subtypes, 4 meningeal sarcomas) and 23 secondary meningeal tumors (8 metastatic carcinomas, 6 gliosarcomas, 9 anaplastic gliomas) with anti-F XIIIa antibody. All HPC revealed 5%-20% of F-XIIIa-positive neoplastic cells. Malignant fibrous histiocytomas and gliosarcomas with MFH-like structures also exhibited multiple F-XIIIa-positive cells. Most of the F-XIIIa-positive cells in meningiomas were identified as macrophages. Furthermore, there was a population of small dark cells of uncertain histogenesis. Cells with positive immunoreactivity for F-XIIIa in metastatic carcinomas and gliomas apparently were of macrophage lineage. Though, in some cases, it would have been difficult to distinguish reactive from neoplastic cells without simultaneous immunohistochemical investigation with antibodies for macrophages, cytokeratin, EMA and GFAP. Because of these uncertainties, wo believe that the potential of F XIIIa-antibody in obtaining precise differential diagnostic information is limited.
