title: [Two cases of multifocal colorectal cancer--polypoid tumor of the colon and small flat carcinoma of the rectum].
abstract: The two cases of multifocal colorectal cancer are described and the proximal tumors are located at right and left colon. The distal tumors are small flat rectal carcinomas, rear with bad prognosis and the first scientific reports for this kind of lesions are dated from less than 20 years. The authors prefer colonoscopy instead of irigography for the diagnosis of the small flat colorectal carcinoma because of the limited possibilities of irigography for lesions less than 2 cm. It is necessary to perform intraoperative endoscopy for the exact localization of the small lesion of the rectum that define the level of resection. Different surgery tactics are applied determinably of the site of the polypoid tumor. In the case when the large tumor was localized in the right colon the operation is finished with temporary ileostomy. In the other case left-colectomy with Dixon's operation are done. The study is interesting because of the rare cases of the small flat carcinoma of the colon.
