In addition to 1 case located in the cecum, the rest were located in the rectum, rectosigmoid and sigmoid colon. Most patients are between 40 and 70 years of age. There is no gender difference. Common symptoms are bloody stools, mucous stools and abdominal pain. Preoperative biopsy was compared with postoperative histological examination, and the misdiagnosis rate was 47.3%. The malignant rate of tumors is as high as 76.3%. Complete removal of the tumor must be performed and a complete histological examination is performed before a correct diagnosis can be obtained. Once the tumor has developed into infiltrating cancer, radical surgery should be performed.
