“…The size of these solitary polyps was also considerable compared to the small polyps usually encountered in cap polyposis. The polyp in our case was approximately 6 cm in diameter and 7 cm in the patient presented by Obusez et al [23] . The sites most commonly afflicted are the rectum and sigmoid colon.…”

“…The polyps are multiple. In fact, only 2 cases of cap polyposis from those reviewed involved a solitary lesion, our patient and the patient reported by Obusez et al [23] in which the polyp was located in the ileal J-pouch. The size of these solitary polyps was also considerable compared to the small polyps usually encountered in cap polyposis.…”

“…One of the aforementioned patients exhibited concurrent lesions in the stomach [12] . One was diagnosed with cap polyposis of the stomach solely during gastroscopy and finally, 1, who had been submitted to restorative proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis, was diagnosed with a cap polyp in the ileal pouch [23] .…”

“…The presence of infection has also been investigated in the pathogenesis of cap polyposis [13,20] despite the fact that pathogens have not been isolated and broad-spectrum antibiotics such as levofloxacin were ineffective. The effectiveness of treatment with metronidazole seems to be the result of the anti-inflammatory rather than the antibacterial properties of the drug, functioning as a free radical scavenger [8,13,23] . The role of inflammatory response in the presence of cap polyposis has been implicated by additional data, such as the development of cap polyps on an anastomotic line, since the process of wound healing on the anastomosis is known to involve a complex network of numerous inflammatory cells and their secretory products, including TNF-a, which accelerates the wound healing process by inducing angiogenesis, fibroblast proliferation and production of several growth factors [19] .…”

Rectal bleeding combined with the presence of a rectal mass has been traditionally associated with the presence of malignant disease. Cap polyposis is a relatively young and still undefined rare entity which mainly involves the rectosigmoid. It is characterized by the presence of inflammatory polyps. In this case report, we present a patient who was diagnosed with a solitary cap polyp of the rectum during the investigation of a bleeding rectal mass. The patient's age and the absence of family history were not in favor of malignancy, despite the strong initial clinical impression. After confirmation of the diagnosis, the patient underwent a snare excision and remains asymptomatic. Cap polyposis, although rare, should be suspected and, when diagnosed, should be treated according to location, number of polyps and severity of symptoms.

Cap polyposis (CP) is an under recognized form of non-neoplastic colonic polyps, characterised by the presence of inflammatory polyps with a distinct “cap” of granulation tissue. CP is often seen masquerading as chronic inflammatory bowel disease. The most common symptoms are mucoid diarrhoea, bloody stools, abdominal pain, and tenesmus. In this case report, we present a patient who was diagnosed with CP during the investigation of unexplained chronic long standing anemia secondary to intermittent rectal bleeding. CP, although rare, should be considered in the differential diagnosis of patients presenting with intermittent rectal bleeding and mucoid diarrhoea.
