New Facets of Hematolymphoid Eponymic Diseases

Disease eponyms can be confusing, difficult to remember, scientifically non-robust, and lacking in implications on and relationships with cell lineage, histogenesis, and pathogenesis. This review is geared toward revisiting hematolymphoid diseases with eponyms in light of recent advances in technology and science by searching the past fifty years of the literature using Scopus and Google Scholar with the keywords “eponyms, hematolymphoid, diseases, lymphoma, benign, malignant, lymph node, spleen, liver, bone marrow, leukemia”. With advances in science and technology, there is accumulation of information on the morphologic nuances and immunologic, immunophenotypic, and genetic features of various hematolymphoid eponymic diseases, thus shedding light on important issues of etiology and pathogenesis with implications on therapy in various non-neoplastic (Castleman, Evans syndrome Kikuchi–Fujimoto, IgG4-related diseases) and neoplastic (Hodgkin, Burkitt, NK/T-cell lymphomas, dendritic/histiocytic neoplasms, and Sezary syndrome) diseases. This contributes to modern nomenclature, classification, subtyping, prognostication, and discoveries on new treatment strategies of hematolymphoid eponymic diseases.
