molecular neuropathology
Subspecialty integrating genetic and molecular analysis with traditional histopathology for brain tumor diagnosis.
Full Definition
A specialized field within neuropathology that combines traditional histomorphological assessment with molecular genetic techniques to provide integrated diagnoses of CNS tumors. This approach incorporates analysis of gene mutations, chromosomal alterations, methylation patterns, and protein expression profiles to classify tumors according to current WHO criteria. Molecular neuropathology has revolutionized brain tumor classification by identifying biologically relevant subgroups with distinct therapeutic targets and prognostic implications, moving beyond purely morphological classification systems.
