Abstract

Hodgkin and Reed/Sternberg (HRS) cells are the hallmark cells of Hodgkin's lymphoma (HL). They are large, often multinucleated with a peculiar morphology and an unusual immunophenotype, that does not resemble any normal cell in the body. Despite their rarity in HL tissues, HRS cells are the clonal tumour cells of HL. HRS cells in nearly all cases of HL derive from B cells, and only rarely from T cells. Notably, the pattern of somatic mutations in their rearranged immunoglobulin V genes suggests that they are derived from pre-apoptotic germinal center B cells. The pathogenesis of HL is still largely unresolved, but it is now clear that aberrant activation of several signalling pathways (such as the NFkappaB pathway) is of key importance for HRS cell survival. HRS or HRS-like cells are also found in several other diseases, e.g. as rare intermingled cells in some non-Hodgkin lymphomas and in infectious mononucleosis.
