    Abstract:
    Conflicting data on the presence of bcl-2/JH gene rearrangement and BCL-2 protein expression in Hodgkin's disease (HD) have been reported. To find out the reason for these differences, well characterized cases from the German National Trial were examined by PCR for the bcl-2 gene rearrangement and immunohistochemically for BCL-2 protein expression. No bcl-2/JH rearrangement could be detected among the HD analyzed from paraffin sections, as well as another 24 cases of HD investigated in fresh tissue. Contrasted with this, immunohistochemistry demonstrated BCL-2 protein expression in all types of HD. In conclusion, our results suggest that the bcl-2/JH gene rearrangement does not play a role in HD, but BCL-2 protein is frequently expressed by RS/H cells of non-lymphocyte predominance subtypes.
