COLON AND RECTUM - Multiple polyposis and carcinoma

The specimen consists of the whole colon and rectum, showing an appendix at one end, and the anus at the other. The whole colon shows multiple polyps of fairly uniform size, with several larger lesions; there is a carcinoma in the ascending colon, in the transverse colon and in the rectum. The carcinoma in the transverse colon is the largest, and shows central ulceration.
