 A man in his sixties underwent total colonoscopy for the diagnostic purpose of abdominal discomfort. Conventional colonoscopy revealed a Is+IIc type tumor in the sigmoid colon. Magnifying colonoscopy with the NBI(narrow band imaging)system showed irregular vessels and a non vascular area in the depressed lesion at the top of the tumor . Magnifying colonoscopy with crystal violet showed VN type pit pattern in the depressed lesion at the top of the tumor. Barium enema revealed obvious deformation in the lateral view. Based on these findings, this tumor was diagnosed as the deeply submucosal or more invasive carcinoma. We operated using laparoscopy-assisted sigmoidectomy. Histopathological examination revealed moderately differentiated adenocarcinoma with invasive micropapillary pattern, tub2(>por1>tub1), type 0-Is+IIc, 15×15×4mm, pSS, pN0(0/4), pStage II, med, INFb, ly1(D2-40), ly(+)(SM), v1(VB-HE), v(+)(SM), pPM0(65mm), pDM0(32mm). The interesting shape of this tumor was molded by the desmoplastic reaction.
