Figure 1 (A) The pathological findings of colonoscopy biopsy. It shows that atypical cells are arranged in an irregular glandular tube-like arrangement, with large and deeply stained nuclei and obvious mitosis (H&E, 40x). (B) The microscopic findings of the resected specimen. There is only mucus but no exact cancer cells were found (H&E, 40x).
