case_images: The duodenal biopsy showed flattened duodenal mucosal epithelium due to marked villous atrophy, hypertrophic crypts, and increased intraepithelial lymphocytes >=30/100 epithelial cells (Figures 1 and 2), which align with the characteristics associated with stage 3b of the modified Marsh classification.  
case_images: The biopsy image (H&E stain x100) of the duodenum demonstrates marked villous atrophy, hypertrophic crypts, and increased intraepithelial lymphocytes, consistent with stage 3b of the modified Marsh classification.
