Hodgkin's disease with CD 20 (B1) positive Reed-Sternberg cells--an immunohistochemical and immunoelectron microscopic study.
20 cases of Hodgkin's disease, [five nodular sclerosis (NS), 12 mixed cellularity (MC), and three lymphocytic depletion (LD)] were studied immunohistochemically and immunoelectron-microscopically to clarify the origin of Reed-Sternberg (RS) cells. The majority of RS cells expressed activated lymphoid cell-associated antigens (CD 30, CD 25, HLA-DR) and granulocyte-associated antigen (CD 15). RS cells in seven cases (one NS, five MC and one LD) reacted with CD 20 (B1). Three of these cases (all three MC) were also positive with CD 19 (B4). These findings suggest that some RS cells may be of B cell lineage.
