Activated microglia in intact white matter immediately bordering an inactive demyelinated plaque (no LFB-positive phagocytes). Numerous foamy microphages were present in demyelinated tissue at the lesion margin. Microglia stain positively for FcγRIII (CD16). The cytoplasm is so lightly stained, however, that the kidney-shaped cell nuclei remain visible (Case 16, CD16 digitally enhanced, ×650).
