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

Figure 2

DLBCL with reactive appearing histocytes in the background (a–c, ×200); IHC staining for CD68 showed the variable intensity of CD68-positive histiocytic cells in the background of lymphoma cells (high, moderate, and low (d–f, respectively, ×200)). IHC for MMP9 showed the variable intensity of histocytes in the background of lymphoma cells (low, moderate, and high (g–i, respectively, ×200).
