Colonic cast. H&E stain. (WC)

LM ischemic colorectal wall (ghost-like crypts without nuclei, muscle without nuclei), mild inflammation
LM DDx infectious colitis
Gross membranous material, fish bladder-like
Site colon

Associated Dx ischemic colitis, atherosclerosis
Clinical history typically post-AAA repair or after colorectal surgery
Prevalence rare
