Core Tip
Core tip: A 72-year-old-man had gastric adenocarcinoma and esophageal squamous cell carcinoma (SCC); the gastric cancer was resected by endoscopic submucosal dissection (ESD), and the esophageal cancer was treated by radiation therapy two months after the ESD. The post ESD scar was found to be elevated and ulcerated during follow-up examination nine months after ESD, and the biopsy specimens showed SCC. It was strongly suspected that the lesion was the result of implantation of esophageal cancer onto the post-ESD ulcer, because the tumor was located immediately under the scar, and there were no similar lesions suggesting hematogenous or lymphatic metastasis.
