He underwent an exploratory laparotomy that revealed multiple small lesions in the small intestine suggestive of malignancy, causing a distal jejunal intussusception responsible for the obstruction. The patient underwent resection of the affected bowel segment and subsequent intestinal anastomosis, with histopathological samples confirming metastatic melanoma. The patient progressed with an adequate postoperative course and is now on a systemic oncology management plan. This case study reports an infrequent presentation of left pinna melanoma intestinal metastases presenting with small bowel obstruction and successful surgical management given to the patient to further broaden knowledge on this subject.<\/jats:p>","DOI":"10.3389\/fsurg.2026.1885354","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T05:44:33Z","timestamp":1790228673000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Small intestine intussusception causing intestinal obstruction secondary to left pinna melanoma metastases: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Jorge Luis","family":"Turizo Farias","sequence":"first","affiliation":[{"name":"Department of Surgery, Hospital Universitario Mayor-M\u00e9deri","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rogers Leonardo","family":"Baquero","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hospital Universitario Mayor-M\u00e9deri","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samir Leonardo","family":"Moreno-Martinez","sequence":"additional","affiliation":[{"name":"School of Medicine and Health Sciences, Universidad del Rosario","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio Alberto","family":"Lesmes","sequence":"additional","affiliation":[{"name":"School of Medicine and Health Sciences, Universidad del Rosario","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofia","family":"Molano Rodriguez","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hospital Universitario Mayor-M\u00e9deri","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juana Gabriela","family":"Rueda","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hospital Universitario Mayor-M\u00e9deri","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella","family":"Van-Londo\u00f1o","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hospital Universitario Mayor-M\u00e9deri","place":["Bogot\u00e1, Colombia"]},{"name":"School of Medicine and Health Sciences, Universidad del Rosario","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"B1","volume-title":"Cancer Statistics","year":"2024"},{"key":"B2","doi-asserted-by":"crossref","first-page":"228","DOI":"10.1002\/(SICI)1096-9098(199804)67:4<228::AID-JSO4>3.0.CO;2-A","article-title":"Factors affecting survival following local, regional, or distant recurrence from localized melanoma","volume":"67","author":"Soong","year":"1998","journal-title":"J Surg Oncol"},{"key":"B3","doi-asserted-by":"publisher","first-page":"807","DOI":"10.1016\/0002-9610(78)90171-x","article-title":"Metastatic pattern of malignant melanoma.
