Abstract
We treated a 67-year-old woman who had a minute T3 colorectal cancer with subserosal invasion. A screening colonoscopic examination revealed a small-depressed lesion at the descending colon and the biopsy specimens showed moderately differentiated adenocarcinoma. Endoscopically, the tumor seemed to invade massively into the submucosal layer or a deeper layer because of positive non-lifting sign. So left hemicolectomy was performed. Resected specimen showed a superficial carcinoma type IIc, measuring 8×7mm in diameter. Microscopi-cally, the tumor was moderately differentiated adenocarcinoma, and which invaded into the subserosal layer without lymph nodes metastasis.
