Immunoglobulin V Genes in Reed–Sternberg Cells

Abstract
Hummel et al. (Oct. 5 issue)1 report the polyclonality of Reed–Sternberg cells in 6 of 12 cases of Hodgkin's disease. In three other cases, there were mixed polyclonal and monoclonal populations of Reed–Sternberg cells, and in three cases the cells were monoclonal. We are concerned about the reported results of this study.
