Figure 2: Photomicrographs showing an admixture of lymphocytes, neutrophils, and histiocytes (a, Hematoxylin and eosin [H and E] ×200). Higher magnification showing emperipolesis of lymphocytes in the histiocytes (b, H and E × 400). These histiocytes are immunopositive on S-100 and CD68 staining (c and d, ×400 each)
