Colorectal cap polyposis:a clinicopathological analysis of fifteen cases with review of literature

Objective To analyze the clinicopathological characteristics,diagnosis and prognosis of colorectal cap polyposis.Methods All cases of colorectal cap polyposis diagnosed pathologically in the Department of Pathology,Beijing Anorectal Hospital from 2018 to 2020 were collected,and a clinicopathological analysis was carried out with review of the literature.Results There were 15 cases of colorectal cap polyposis in this group.The male to female ratio was 2∶1.The average age was 40 years,with range from 17 to 68 years.Hematochezia occurred in all cases,proctitis occurred in 5 cases,and rectal prolapse and constipation occurred in 10 cases.The diameter of the tumor was 0.3-3.0 cm,14 cases were multiple and 1 case was single.Among them,1 case of cap polyposis with tubular adenoma,1 case of cap polyposis with squamous epithelial low?grade intraepithelial neoplasia.Of the 15 cases,12 occurred in the rectum,2 in the sigmoid colon,and 1 in the ascending colon and descending colon.Follow up for 3-36 months showed that 15 cases were alive,and 6 cases had recurrence.The recurrence was all frequently present in multiple polyposis cases,of which 4 cases were polyp ring grown within intestinal lumen,and 2 cases were complicated by severe chronic inflammation,which was prolonged and unhealed.Conclusion All patients with colorectal cap polyposis are present in the lower gastrointestinal tract.The number and size of the underlying diseases and polyposis are closely related to the treatment method.Endoscopy helps find the lesions and the pathological diagnosis is finally confirmed.Long?term stimulation of the tumor will not cause malignancy,but treatment must be directed to the original disease,otherwise it will easily cause recurrence and misdiagnosis.
