The classification and diagnosis of lymphoma have evolved significantly over the last 20 years, moving from a simplistic system reliant on H&E sections to a more complex multidisciplinary approach that includes immunophenotyping and molecular studies.
The transition began with early classifications like Kiel and REAL, ultimately leading to the current WHO classifications that incorporate various clinical features, morphological data, and genetic information.
This modern process demands cooperation among multiple specialized laboratories and integration of diverse diagnostic findings into a comprehensive report for accurate diagnosis of lymphoproliferative disorders.
