Abstract
Neurocytoma accounts for 0.5% of all tumors of the central nervous system. 18 such tumors are described. Homogeneous expression of neuron-specific enolase and synaptophysin and heterogeneous expression of PCNA and some proteins are characteristic for these tumors. Two immunophenotypic variants are distinguished: p30-32 positive tumors with high values of PCNA; c-er B-2 HSPh-highly positive variant with lower indices of the "growth fractions".
