Rectal growth. Gross specimen of a villous growth in the rectum, the final section of the digestive tract where faeces are stored before defecation. A villous growth refers the folded appearance of the growth, similar to the villous folds (villi) found in the intestinal tract. Such growths often arise from the glandular epithelium, and are then called villous adenomas. Rectal growths (polyps) should be surgically removed in case they turn cancerous.
