Figure 2 Immunohistochemical staining was positive for CD-56, synaptophysin, and pan-cytokeratin. A: Positive reaction for CD56 in tumor cells (magnification × 200); B: Positive reaction for synaptophysin in tumor cells (magnification × 200); C: Positive reaction for pan-cytokeratin in tumor cells (magnification × 200); D: Pathology by biopsy from the stomach (hematoxylin eosin staining) showed cancer cells around the gastric mucosal glands (magnification × 100).
