Abstract
A case of a pedunculated adenomatous polyp of the sigmoid colon was found to have a primary focus of signet ring cell carcinoma. Histologic examination of the medium-sized polyp was consistent with an adenoma to carcinoma sequence for signet ring cell carcinoma of the colon, similar to that for the common adenocarcinomas.
