Hodgkin's disease: old and recent clinical concepts.
The diagnosis of Hodgkin's disease (HD) is still primarily based on the histopathologic criteria presented by Lukes et al in 1965. Over the past three decades, however, advances in immunohistochemistry, molecular studies, and virologic findings have provided evidence that HD exhibits significant heterogeneity. Whereas the nodular sclerosis subtype is the major subset of the "classic" disease, it has become evident that the nodular, lymphocytic predominance subtype may represent a minor distinct subset, and possibly a distinct disease entity. Furthermore, there is strong evidence that the mixed cellularity subtype may be an Epstein-Barr virus-related disorder. Finally, based on phenotypic and genotypic features, the existence of a "continuum" between a fraction of HD cases, including the lymphocytic depletion subtype, and CD30-positive anaplastic large cell lymphomas has been suggested.
