Treatment for gastric ‘indefinite for neoplasm/dysplasia’ lesions based on predictive factors

Figure 2 Representative cases of undifferentiated carcinoma. Flat lesions with color change (A-C) and fold change with ulcerations (D-F) are shown at endoscopy. G: The case in panel A shows a few tumor cells (magnified in the inlet) in the endoscopic biopsy specimen (black arrow). H: The resected specimen shows poorly differentiated tubular adenocarcinoma with a very small tumor size (0.7 cm × 0.6 cm). I: The case in panel B shows a few tumor cells in the endoscopic biopsy specimen (black arrow). J: The resected specimen shows mixed signet ring cell carcinoma and poorly differentiated tubular adenocarcinoma with a very small tumor size (0.6 cm × 0.4 cm). K: The case in panel e shows a few tumor cells as squeezing artifact-like clusters in the endoscopic biopsy specimen (black arrow). L: The resected specimen shows mixed poorly differentiated (dotted arrow) and well-differentiated (red arrow) tubular adenocarcinoma.
