Figure 1. Histological analysis of the gastric ulcer biopsy showing malignant glandular proliferation (A, H&E, × 10), tumor cells exhibiting high nuclear to cytoplasmic ratio, prominent nucleoli, and frequent mitotic figures (B, H&E, × 40). There are areas of ulceration with tissue necrosis (C, H&E, × 10) and areas of lymphocytic infiltrate, morphologically consistent with reactive process (D, H&E, × 10).
