Objective To be investigated the morphology of colorectal small flat adenoma and the expressions of p53 , p21, ER and PR. Methods Colonoscopy ( Olympus CF 240) and microscopy ( Olympus BV 41) were used to observe 50 cases of colorectal small flat adenomas. The expressions of p53 , p21 , ER, and PR were detected by the two steps of immunohistochemistry in 50 cases of small flat adenomas and the surrounding mucosa, 26 cases of colorectal carcinomas, while 15 cases of the normal colorectal mucosa as control group. Results These lesions were distributed throughout the large bowel, the prevalence in order was transverse colon, sigmoid and rectum. The small flat adenoma was round, flat, or sessile in shape, and sized
