Increased T lymphocytes and IgMEA-receptor lymphocytes in Hodgkin's disease spleens

Splenic lymphocytes from 11 patients with Hodgkin's disease were compared to lymphocytes of six spleens from patients with nonlymphoproliferative diseases. T lymphocytes were increased in patients with histological involvement by Hodgkin's disease. Likewise, lymphocytes from spleens with histological involvement showed increased rosette formation with immunologlobulin M-coated sheep red blood cells (IgMEA). A similar increase in T lymphocytes and in IgMEA rosette formation was not observed with normal peripheral blood lymphocytes, control spleens, or with Hodgkin's disease spleens without evidence of histological involvement.
