The clinical, light microscopic and electron microscopic pictures of a sarcomatous meningioma are reported.
In the electron microscopic structure of the tumor changes are observed in the nucleus, as well as in the cytoplasma, witnessing an increased cellular metabolism. Besides peculiar inplasmic bodies with a net-like granular structure are also seen.
It is possible that the latter are the product of degeneration or regeneration or even the nucleoid of virus-like formations.
