Figure 1 Endoscopic features of lesions.
A: Whitish, shallow, and uneven mucosa lesions with minimal spontaneous bleeding at gastric antrum; B: The tumor invades gastric antrum and angular notch; C: Magnifying endoscopy with narrow-band imaging reveals typical tree-like appearance microvessels; D: Indigo carmine chromoendoscopy delineates a poor-demarcated lesion with an irregular margin.
Figure 2 Histopathology of the stomach specimens removed through surgery.
A: Low-power micrograph of gastric tumor (hematoxylin and eosin stain, × 40); B: High-power micrograph of signet ring cells and lymphoid follicular hyperplasia (hematoxylin and eosin stain, × 400); C: CD20 stain shows strong and diffuse cytomembrane immunoreactivity confirming gastric mucosa-associated lymphoid tissue lymphoma (× 400); D: Pan-cytokeratin stain shows strong and diffuse cytoplasmic immunoreactivity confirming signet-ring cell carcinoma (× 100).
