Figure 5 Pathology of the gastric antrum lesion. A: Tumor cells arranged in clusters with a micropapillary pattern (hematoxylin and eosin [H&E], 200 ×); B: Tumor cells exhibiting cord-like or linear arrangements (H&E, 200 ×); C: In certain regions, tumor cells appeared in cord-like or linear patterns, with scattered signet ring cells present within a mucinous background (H&E, 100 ×); D: The majority of tumor cells were moderately large, displaying fine chromatin, inconspicuous nucleoli, and readily identifiable mitotic figures; Some nuclei were eccentrically displaced (H&E, 400 ×); E: Signet ring cells within the mucinous background showed marked atypia, with visible nucleoli (H&E, 400 ×).
