Submucosa present POLYP, ASCENDING COLON, BIOPSY: COLONIC MUCOSA WITH MORPHOLOGICALLY BENIGN LYMPHOID AGGREGATES, RECTAL MUCOSA WITHIN NORMAL LIMITS WITH A MORPHOLOGICALLY BENIGN LYMPHOID AGGREGATE. It is worthwhile to report the presence of lymphoid nodules as they reassure the endoscopist that they probably sampled the abnormality they saw. Lymphoid nodules manifest endoscopically as a small polypoid protuberances.COLONIC MUCOSA AND SUBMUCOSA WITHIN NORMAL LIMITS. Mucosa and submucosa POLYP, SIGMOID COLON, BIOPSY: POLYPOID FRAGMENT OF COLORECTAL-TYPE MUCOSA WITHIN NORMAL LIMITS. Polypoid fragments POLYP, SIGMOID COLON, BIOPSY: COLORECTAL-TYPE MUCOSA WITHIN NORMAL LIMITS. Colorectal mucosa within normal limits. Colorectal-type mucosa within normal limits. the deeper glands are dark blue and the superficial gland are light blue.ДDx (colorectal mucosa with minimal changes):

The surface should be lighter staining than the deeper aspect, i.e.

Deep part of crypt is more hyperchromatic than superficial component - important.

Endoscopists go after anything that is polypoid.

Notes: Left colon refers to the sigmoid colon, descending colon and the distal half of the transverse colon right colon refers to the cecum, ascending colon and proximal half of the transverse colon.

Glands - straight, no branching 'test tube' shape.

This may be difficult to assess histomorphologically these one should show a friend.
