Figure 1.
Figure 1. Endoscopy showed a type 0-IIa early gastric cancer in the anterior wall of the antrum (arrow heads). (a) white light image, and (b) NBI image. NBI: narrow band imaging (c).
Figure 2.
Figure 2. (a-c) The histopathological examination of the resected specimen revealed very well-differentiated tubular adenocarcinoma (tub1) of 30 × 22 mm in size, confined to the mucosa. No lymphovascular invasion or ulceration was observed, there was no undifferentiated-type component, and the margins were tumor-free.
Figure 3.
Figure 3. The follow-up endoscopy showed an irregular, slightly-depressed lesion within the post-ESD scar (arrow heads) (a, b). The lesion showed irregular microvessels on magnifying NBI (arrow heads) (c).
Figure 4.
Figure 4. Endoscopic ultrasonography revealed broad hypoechoic fibrotic lesion up to the shallow submucosal layer (arrows).
Figure 5.
Figure 5. (a-c) A histopathological examination of the resected specimen revealed well-differentiated tubular adenocarcinoma (tub1) of 6 × 4 mm in size, confined to the mucosa. No lymphovascular invasion was detected and the margins were tumor-free.
