In this review we have attempted to present the development of current nosology in a manner that will help incorporate recent classifications into daily use.

The early classification of lymphomas into giant-follicle lymphoma, lymphosarcoma, and reticulum cell sarcoma² did not accurately describe the wide variation in histological and clinical manifestations of the lymphoproliferative diseases. Therefore, there was a need for a better scheme of classification.
