The sections show colonic mucosa with abundant intraepithelial lymphocytes (>20 lymphocytes/100 surface epithelial cells). A prominent collagen band is apparent below the epithelium (>10 micrometres thick). The glandular architecture is within normal limits. | The sections show colonic mucosa with abundant intraepithelial lymphocytes (>20 lymphocytes/100 surface epithelial cells).
