Patterns of presentation of Hodgkin disease. Implications for etiology and pathogenesis

Abstract

This study supports the conclusion that NS and MC Hodgkin disease spread by continguity, most often originating in the neck or mediastinum, and is consistent with evidence suggesting an infectious agent in the pathogenesis of these subtypes of Hodgkin disease. In contrast, LP Hodgkin disease is characterized by different sites of presentation and patterns of spread. This suggests that two or perhaps three clinicopathologic subtypes of Hodgkin disease exist. Implications for etiology and pathogenesis are discussed.
