Fig. 4From: Kimura’s disease affecting multiple body parts in a 57-year-old female patient: a case reportImmunohistochemical stains of excisional retroauricular lymph node shows reactive hyperplasia expression form. (EnVision two-step stain, ×40). a CD3 is expressed by numerous T cells located in interfollicular zone, fewer T cells in follicular germinal center, mostly of Th cells, b CD20 is expressed by abudantly hyperplastic reactive Lymphoid follicles, c CD21 highlights nodular FDC network. d BCL-2 stainning shows the germinal center of hyperplastic follices negative, but mantle zone of follicles and interfollicular zone positive, e Ki-67 stainning indicates the proliferation index of lymphocytes in germinal center of secondary follicular germinal centers high expressionBack to article page
