Immunohistochemical analysis of representative testicular DLCL cases.
Immunohistochemical staining was performed with the use of (A) the MoAb HCA2 (anti-HLA-A) (T20) and (B) the MoAb clone B8.11.2 (HLA-DR) (T18) (original magnification × 40). Note the positive (brown) staining in the internal control cells scattered through the mass of negative lymphoma cells.
