Adenomatous Polyp of the Colon

This 2.5-centimeter adenomatous polyp was serendipitously found in a right colectomy specimen. The colon was removed to bypass an extrinsic obstruction caused by metastatic ovarian cancer. In the picture above, the long axis of the opened bowel is horizontal, and the mucosa is viewed en face.

Both photos were shot with an Olympus D-600L digital camera mounted on a copystand illuminated by 4 photofloods. In the top picture, the specimen was submerged in water, while the specimen in the bottom picture was shot dry.
