Prognostic Role of Tumor Microenvironment in DLBCL and Relation to Patients’ Clinical Outcome: A Clinical and Immunohistochemical Study

Figure 1

DLBCL with reactive appearing lymphocytes in the background (a–c, ×200); IHC staining for CD4 showed the variable intensity of CD4-positive T helper cells in the background of lymphoma cells (high, moderate, and low (d–f, respectively, ×200)). IHC for CD8 showed the variable intensity of CD8-positive cytotoxic T cells in the background of lymphoma cells (low, moderate, and high (g–i, respectively, ×200)).
