Immunohistochemical identification and quantification of S100+ dendritic cells in two different SINs. A central slice of each immunized lymph node was preserved in formalin and evaluated by immunohistochemical stains for S100+ dendritic cells. The proportion of the cross-sectional area occupied by DC ranged from about 2% to 20%. Examples are shown for patient VMM226 (A, B) with 6.6% of the lymph node containing S100+ dendritic cells and for VMM193 (C, D) with 2.7% of the lymph node containing S100+ dendritic cells. Histologically, the lymph node from patient VMM226 (A) had reactive features, whereas the lymph node from patient VMM193 (B) did not have reactive features. (A) and (C) were at an original magnification of 20× with the boxed areas approximately corresponding to (B) and (D); (B) and (D) were at an original magnification of 100×.
