 A case of a man in his seventies. Transnasal endoscopy showed the lesion suspected to be early gastric cancer, in the health examination. However the histological finding was Group1 at the first biopsy. Another day, we carried out conventional endoscopy, and the secondary biopsy examination resulted in well-differentiated adenocarcinoma. ESD(endoscopic submucosal dissection)was performed, and the pathlogical diagnosis was gastric adenocarcinoma, pType0-IIc, 20×10mm, tub1, pT1a(M), ly0, v0, HM0, VM0, UL(-). In transnasal endoscopy, pictures are more important because biopsy is sometimes difficult. We must carry out conventional endoscopy when we cannot find the histological evidence that we assume.
