 A male in his 70's was referred to our hospital for further examination and treatment of early colorectal carcinoma. A colonoscopy revealed a 15mm-diameter 0-IIa+IIc lesion with hardness in the central depression in the sigmoid colon. However, magnifying colonoscopy showed a regular pit pattern or VI pit pattern. Thus, we ruled out deep submucosal invasive carcinoma. We conducted endoscopic submucosal dissection to perform an excisional total biopsy. Histopathological examination revealed well-differentiated adenocarcinoma(tub1)with shallow submucosal invasion(T1a;submucosal, 600μm), no vessel involvement, and negative tumor margin(curative resection).
