Immunohistochemistry for COX-2 in colorectal neoplasias. A. No overexpression in colorectal adenoma (arrow). Inflammatory cells serve as an internal positive control (empty arrow). B. Weak (1+) overexpression in colorectal adenoma (arrows). C. Strong (2+) overexpression in colorectal adenoma (arrows). Note a junction between adenoma and normal appearing colon (empty block arrow). D. Strong (2+) overexpression in colorectal adenocarcinoma (arrows).
