Adult intussusception is usually associated with an underlying organic pathology, such as a benign or malignant tumour which acts as the lead point. Prolapse of the lead-point mass through the anal canal is an extremely rare presentation with very few reported cases in the literature. We describe a case of a 67-year-old man who presented with rectal prolapse of a large soft tissue mass. CT of the abdomen and barium enema revealed partial intussusception of an upper\u00a0sigmoid lipomatous polyp. Examination under anaesthesia was performed and the prolapse reduced. A laparoscopic sigmoid colectomy was planned. The patient subsequently re-presented clinically unwell with a recurrent necrotic prolapsing mass. Laparotomy and sigmoid colectomy was performed and the patient recovered fully. The resected mass was a 7\u00d74.5\u00d74.0\u2005cm necrotic sigmoid lipoma.<\/jats:p>","DOI":"10.1136\/bcr-2014-204036","type":"journal-article","created":{"date-parts":[[2014,5,22]],"date-time":"2014-05-22T07:03:14Z","timestamp":1400742194000},"page":"bcr2014204036","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Prolapsed giant sigmoid lipoma: a rare cause of adult ischaemic intussusception"],"prefix":"10.1136","volume":"2014","author":[{"given":"Mark","family":"Elliott","sequence":"first","affiliation":[{"name":"Department of Surgery, Causeway Hospital, Coleraine, Northern Ireland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Martin","sequence":"additional","affiliation":[{"name":"Department of Surgery, Causeway Hospital, Coleraine, Northern Ireland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fred","family":"Mullan","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Causeway Hospital, Coleraine, Northern Ireland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,5,22]]},"reference":[{"key":"2025082704082044000_2014.may22_1.bcr2014204036.1","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-199708000-00003"},{"key":"2025082704082044000_2014.may22_1.bcr2014204036.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9610(96)00419-9"},{"key":"2025082704082044000_2014.may22_1.bcr2014204036.3","doi-asserted-by":"publisher","DOI":"10.1002\/jso.21117"},{"key":"2025082704082044000_2014.may22_1.bcr2014204036.4","doi-asserted-by":"publisher","DOI":"10.4240\/wjgs.v3.i1.13"},{"key":"2025082704082044000_2014.may22_1.bcr2014204036.5","first-page":"247","article-title":"Benign small bowel tumor","volume":"181","author":"Wilson","year":"1975","journal-title":"Ann Surg"},{"key":"2025082704082044000_2014.may22_1.bcr2014204036.6","first-page":"420","article-title":"Colonic lipomas.
