WHO classification

WHO classification

Surgical pathology A classification of non-Hodgkins lymphomas based upon an updated version of the REAL classification system; the WHO classification system is currently accepted as the authoritative standard for diagnosing lymphomas; it does not group lymphomas into prognostic categories, but, rather, considers each lymphoma as a separate disease; the WHO system uses morphology, immunophenotyping, and genotyping to classify the malignancy, which is often graded, typically from I to IV. See Non-Hodgkin's lymphoma, REAL classification. Cf Hodgkin's disease, Working formulation.
