Implantation of esophageal cancer onto post-dissection ulcer after gastric endoscopic submucosal dissection

Figure 1 Esophagogastroduodenoscopy findings. A: An elevated lesion 20 mm in size was detected in the left wall of the middle thoracic esophagus. The endoscopic findings indicated that the lesion was esophageal cancer with a depth of SM2; B, C: Biopsy specimens revealed moderately differentiated squamous cell carcinoma (hematoxylin-eosin stain; magnification: B × 40, C × 200); D: A small erosion with surrounding reddish mucosa was also found in the posterior wall of the gastric antrum, which was suspected to be gastric mucosal cancer.
