Fig. 2. Colonic biopsy specimens showing "Indefinite for dysplasia". Low-power photomicrograph shows colonic biopsy in ulcerative colitis with altered crypt architecture and dense mixed inflammation in lamina propria (A, H&E ×40). Focally, the crypt epithelial cells show nuclear stratification and hyperchromasia without prominent nucleoli, (B–D, H&E ×400) in areas adjacent to neutrophilic infiltration (C, arrow), qualifying as indefinite for dysplasia changes.
