We report the case of a woman in her mid-50s who came to the gynaecology clinic with breathlessness and anaemia. Initial imaging with an abdominal ultrasound and pelvic MRI showed a 4\u00d74\u00d74\u2009cm pelvic mass, suspected to be a wandering fibroid, and surgical removal was planned. During the surgery, the mass was unexpectedly found to come from the jejunum. The general surgery team was consulted, and a 4\u00d74\u00d74\u2009cm mass outside the jejunum was removed, initially thought to be a gastrointestinal stromal tumour (GIST). However, the histopathological exam showed that the lesion was an IFP, confirmed by immunohistochemistry, which tested negative for CD117. Unlike GISTs, IFPs are completely benign, have no chance of becoming cancerous and rarely come back after full removal. Extraluminal cases of IFPs are extremely rare in the literature. Recognising these unusual cases is crucial to prevent misdiagnosis, guide proper surgical management and reassure patients about their prognosis.<\/jats:p>","DOI":"10.1136\/bcr-2024-264292","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T16:20:12Z","timestamp":1770049212000},"page":"e264292","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Extraluminal inflammatory fibroid polyp mimicking as wandering fibroid\/GIST"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4108-3351","authenticated-orcid":false,"given":"Haridev","family":"Sankar","sequence":"first","affiliation":[{"name":"General Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naveen","family":"Alexander","sequence":"additional","affiliation":[{"name":"General Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bhuvaneshwari","family":"Harikrishnan","sequence":"additional","affiliation":[{"name":"General Surgery, Sri Ramachandra Institute of Higher Education and Research, Chennai, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,2,2]]},"reference":[{"key":"2026020208200627000_19.2.e264292.1","first-page":"397","article-title":"Gastric submucosal granuloma with eosinophilic infiltration","volume":"25","author":"Vanek","year":"1949","journal-title":"Am J Pathol"},{"key":"2026020208200627000_19.2.e264292.2","doi-asserted-by":"crossref","first-page":"5745","DOI":"10.3748\/wjg.v18.i40.5745","article-title":"Intussusception due to inflammatory fibroid polyp: A case report and comprehensive literature review","volume":"18","author":"Akbulut","year":"2012","journal-title":"WJG"},{"key":"2026020208200627000_19.2.e264292.3","doi-asserted-by":"crossref","first-page":"304","DOI":"10.5582\/irdr.2017.01060","article-title":"Inflammatory fibroid polyp of the gastric antrum presenting as hypovolemic shock: Case report and literature review","volume":"6","author":"Klingbeil","year":"2017","journal-title":"IRDR"},{"key":"2026020208200627000_19.2.e264292.4","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000006131","article-title":"A unique case of inflammatory fibroid polyp in the duodenum of a female adolescent: Case report and literature review","volume":"96","author":"Calderon","year":"2017","journal-title":"Medicine (Baltimore)"},{"key":"2026020208200627000_19.2.e264292.5","doi-asserted-by":"publisher","DOI":"10.1136\/gut.33.7.1004"},{"key":"2026020208200627000_19.2.e264292.6","doi-asserted-by":"publisher","DOI":"10.1002\/path.2393"},{"key":"2026020208200627000_19.2.e264292.7","doi-asserted-by":"crossref","first-page":"106947","DOI":"10.1016\/j.ijscr.2022.106947","article-title":"Inflammatory fibroid polyp (Vanek\u2019s tumor) causing double compound ileo-ileal intussusception in an adult patient, a case report","volume":"93","author":"Gadoura","year":"2022","journal-title":"Int J Surg Case Rep"},{"key":"2026020208200627000_19.2.e264292.8","first-page":"640","article-title":"Gastric polyps: a review of clinical, endoscopic, and histopathologic features and management decisions","volume":"9","author":"Islam","year":"2013","journal-title":"Gastroenterol Hepatol (N Y)"},{"key":"2026020208200627000_19.2.e264292.9","doi-asserted-by":"publisher","DOI":"10.1007\/s00018-020-03753-y"},{"key":"2026020208200627000_19.2.e264292.10","first-page":"441","article-title":"Inflammatory Fibroid Polyp of the Ileocecal Valve: Case Report, Review, and Recent Advances","volume":"45","author":"Smith-Chakmakova","year":"2015","journal-title":"Ann Clin Lab Sci"},{"key":"2026020208200627000_19.2.e264292.11","doi-asserted-by":"publisher","DOI":"10.21873\/invivo.12235"},{"key":"2026020208200627000_19.2.e264292.12","doi-asserted-by":"crossref","unstructured":"Toydemir T .
