Conversely, classic HD ( CHD ) is heterogeneous because the tumor cells of a fraction of CHD display the BCL-6 (-)/ syn-1 (+) phenotype of post-GC B-cells, whereas another fraction of CHD is constituted by a mixture of tumor cells reflecting the GC ( BCL-6 (+)/ syn-1 (-)) or post-GC ( BCL-6 (-)/ syn-1 (+)) phenotypes .
