Gastric ectopic pancreas combined with synchronous multiple early gastric cancer: A rare case report

Figure 1 The major gastric lesion. A: White light imaging demonstrating a heart-shaped lesion. The demarcation line is highlighted with a yellow dashed line. The arrow indicates the ectopic pancreatic opening; B: Indigo carmine dying; C and D: Narrow band imaging combined with magnifying endoscopy; E and F: Endoscopic ultrasound demonstrating hypoechoic changes, uneven internal echoes and unclear boundaries between some areas and muscularis propria in the major lesion.

Figure 2 The minor gastric lesion. A: White light imaging. The demarcation line is highlighted with a yellow dashed line; B-D: Narrow band imaging combined with magnifying endoscopy.

Figure 3 Histopathological specimen showing high-grade intraepithelial neoplasia of the gastric body lesion after endoscopic submucosal dissection. A: hematoxylin-eosin staining (40×); B: hematoxylin-eosin staining (200×).
