摘      要：A case in which implantation of esophageal squamous cell carcinoma onto a post-dissection gastric ulcer was strongly suspected is presented. A 72-yearold man with alcoholic liver cirrhosis underwent esophagogastroduodenoscopy(EGD). Esophageal cancer(EC)(Mt, 20 mm, 0-Is) and gastric cancer(GC)(antrum, 15 mm, 0-Ⅱc) were identified. Biopsy specimens revealed moderately differentiated squamous cell carcinoma(SCC) and differentiated adenocarcinoma, respectively. The GC was resected by endoscopic submucosal dissection(ESD) [14 mm × 9 mm, type 0-Ⅱc, tub1, p T1a(M), ly0, v0, HM(-), VM(-)]. Two months after ESD, radiation therapy was started for the EC, and an almost complete response was obtained. Nine months after the ESD, a follow-up EGD showed a submucosal tumor-like lesion with ulceration, located immediately under the post-ESD scar, and biopsy specimens showed moderately differentiated SCC. There were no similar lesions suggesting hematogenous or lymphatic metastasis in the stomach.
