Frontal brain. Immunohistochemistry for CD68 (expressed by monocytic cells). Note map-like tissue destruction with the presence of CD68-positive microglial cells. Furthermore zonal activation of microglia (brown granules). Activation of the microglia means that tissue destruction has taken place in the brain, which is cleared/removed by macrophages (called microglia in the brain). Brown granules: macrophages/microglia.
