Figure 1. Histological photomicrographs for the peripheral follicular helper T-cell phenotype (breast): (A) A population of small atypical lymphocytes with a diffuse growth pattern, admixed eosinophils are present (hematoxylin and eosin stain, low magnification ×20) (B) The lymphocytes showed clear cytoplasm and dark nuclei with irregular profiles and small nucleoli. Eosinophils are also evident (hematoxylin and eosin stain, high magnification ×40). (C) Immunohistochemical stains showed a T-cell phenotype: CD5 (magnification ×10). (D) Immunohistochemical stains showed a T-cell phenotype: CD3 (magnification ×20). (E) Helper T-cell markers were present in the T-cell population as revealed by strong PD1 (magnification ×10). (F) Immunohistochemical stains showed a T-cell phenotype: CD4 (magnification ×4). (G) Proliferation index Ki67 60% to 70% (magnification ×10).
