Objective: To evaluate the clinicopathological characteristics of rectal cancer diagnosed as adenoma in biopsy. Methods: 50 rectal cancer cases diagnosed as adenoma in biopsy were analyzed retrospectively in this study by comparing the biopsy and postoperative pathology. Results: Among these 50 patients, biopsy pathology showed 26% (13/50) adenoma with mild dysplasia, 30% (15/50) adenoma with moderate dysplasia, and 44% (22/50) adenoma with severe dysplasia. In 8 cases, the adenomas were smaller than 2cm. On postoperatively surgical pathology, only 10 cases were carcinoma-in-situ, while 40 cases were invasive cancer. Conclusion: Special emphasis should be taken to biopsy-negative rectal adenomas and those smaller than 2cm.
