Figure 1 Colon biopsies in DIC, acute GVHD, and CMV colitis. All biopsies show similar histologic findings with scattered apoptotic bodies in glandular crypts (red arrows) and mild chronic inflammatory infiltrate. In addition, reddish intranuclear inclusions (black solid arrow) are seen in CMV colitis, confirmed by CMV immunostain (inset) (H&E, ×60, CMV immunohistochemistry, ×60).

Figure 2 Characterization of lymphocytic infiltrates in DIC and acute GVHD. Both biopsies show similar infiltration in lamina propria and crypt epithelia of predominantly CD3 and CD8-positive cytotoxic T cells. CD56-positive natural killer cells are rare in the epithelium. (CD3, ×60; CD8, ×60; CD56, ×60).
