The patient presented with a 1-month history of rectal bleeding, mucoid discharge, and severe colicky abdominal pain due to intussusceptions. On colonoscopy, there was an exophytic mass with surface exudates. Colonic resection and anastomosis were performed, due to recurring partial intestinal obstruction. At a 6-month follow-up, the patient was asymptomatic.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Inflammatory cap polyp is a benign entity, and it should be kept in mind as an important differential diagnosis of exophytic colonic mass with surface exudates.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13256-021-02857-8","type":"journal-article","created":{"date-parts":[[2021,5,28]],"date-time":"2021-05-28T23:14:07Z","timestamp":1622243647000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Inflammatory cap polyp of the sigmoid colon: a case report"],"prefix":"10.1186","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6904-7972","authenticated-orcid":false,"given":"Narendra","family":"Pandit","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tek Narayan","family":"Yadav","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mona","family":"Dahal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laligen","family":"Awale","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shailesh","family":"Adhikary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,5,29]]},"reference":[{"issue":"4","key":"2857_CR1","doi-asserted-by":"publisher","first-page":"378","DOI":"10.1177\/1066896913501383","volume":"22","author":"G De Petris","year":"2014","unstructured":"De Petris G, Dhungel BM, Chen L, Pasha SF.
