This patient had no significant medical or surgical history and presented to the emergency department with a rectal prolapse which had become incarcerated and increasingly painful over the previous 2\u00a0weeks. A computed tomography (CT) abdomen and pelvis appeared benign, demonstrating a full-thickness rectal prolapse with no definite rectal mass. A colonoscopy was performed, revealing anterior rectal mucosal edema, fibrosis, and a possible mass. This prompted the patient to be taken to the operating room for a low anterior resection of the rectum and sigmoid. A 10.5 \u00d7 8.2 \u00d7 1.9\u00a0cm rectal mass was noted and pathology revealed colonic adenocarcinoma. This case highlights the importance of performing a colonoscopy in patients with atypical rectal prolapse, even when the physical exam and CT appears benign.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf1118","type":"journal-article","created":{"date-parts":[[2026,2,3]],"date-time":"2026-02-03T12:36:58Z","timestamp":1770122218000},"source":"Crossref","is-referenced-by-count":0,"title":["Rectal adenocarcinoma presenting as full-thickness prolapse with external haemorrhoids: case report"],"prefix":"10.1093","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-9933-0883","authenticated-orcid":false,"given":"Samantha","family":"Temucin","sequence":"first","affiliation":[{"name":"Philadelphia College of Osteopathic Medicine , 4170 City Av, Philadelphia 19131, PA ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sean","family":"Singh","sequence":"additional","affiliation":[{"name":"Philadelphia College of Osteopathic Medicine , 4170 City Av, Philadelphia 19131, PA ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerie","family":"Bauer","sequence":"additional","affiliation":[{"name":"Jefferson Health, Department of Surgery , 435 Hurffville -
