Desmoid tumours are usually benign and are locally aggressive tumours. We report a case of a 31-year-old man presenting with abdominal mass associated with dyspepsia and early satiety. CT scan demonstrated a large heterogeneous mass adherent to or arising from the jejunum. The patient underwent a successful elective exploratory laparotomy with resection of the tumour arising from the wall of the ileum with a 10\u2009cm margin. The patient had an uneventful recovery and no recurrence at 6-month follow-up. Pathology report and immunohistochemistry analysis revealed the mass to be a primary desmoid tumour of the small bowel, as the tumour was negative for c-kit and Discovered on GIST 1 (DOG-1) and positive for beta-catenin and smooth muscle actin.<\/jats:p>","DOI":"10.1136\/bcr-2020-237032","type":"journal-article","created":{"date-parts":[[2021,2,22]],"date-time":"2021-02-22T11:36:27Z","timestamp":1613993787000},"page":"e237032","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Intra-abdominal small intestinal desmoid tumour mimicking GIST"],"prefix":"10.1136","volume":"14","author":[{"given":"Sai Krishna","family":"Eswaravaka","sequence":"first","affiliation":[{"name":"Department of General Surgery, Topiwala National Medical College, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3294-9520","authenticated-orcid":false,"given":"Swanit Hemant","family":"Deshpande","sequence":"additional","affiliation":[{"name":"General Surgery, BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roshan","family":"Chiranjeev","sequence":"additional","affiliation":[{"name":"General Surgery, BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jayashri Sanjay","family":"Pandya","sequence":"additional","affiliation":[{"name":"General Surgery, BYL Nair Charitable Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,2,22]]},"reference":[{"key":"2025082804044097000_14.2.e237032.1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2012\/713836","article-title":"Sporadic intra-abdominal desmoid: a rare presentation as a hepatic mass","volume":"2012","author":"Gupta","year":"2012","journal-title":"Case Rep Pathol"},{"key":"2025082804044097000_14.2.e237032.2","doi-asserted-by":"crossref","first-page":"e92","DOI":"10.1055\/s-0039-1694704","article-title":"Gastrointestinal stromal tumors of small intestine","volume":"05","author":"Huda","year":"2019","journal-title":"Surg J"},{"key":"2025082804044097000_14.2.e237032.3","first-page":"662","article-title":"Abdominal pain and colonic obstruction from an intra-abdominal desmoid tumor","volume":"6","author":"Venkat","year":"2010","journal-title":"Gastroenterol Hepatol"},{"key":"2025082804044097000_14.2.e237032.4","doi-asserted-by":"crossref","first-page":"1008","DOI":"10.2214\/AJR.11.6657","article-title":"Raut CP: a to Z of desmoid tumours","volume":"197","author":"Shinagare","year":"2011","journal-title":"Am J Roentgenol"},{"key":"2025082804044097000_14.2.e237032.5","doi-asserted-by":"crossref","first-page":"821","DOI":"10.1177\/000313480607200911","article-title":"An unusual presentation of desmoid tumor in the ileum","volume":"72","author":"Singh","year":"2006","journal-title":"Am Surg"},{"key":"2025082804044097000_14.2.e237032.6","doi-asserted-by":"crossref","DOI":"10.2214\/ajr.183.1.1830118","article-title":"Desmoid tumor of the small bowel and the mesentery","volume":"183","author":"Faria","year":"2004","journal-title":"AJR Am J Roentgenol"},{"key":"2025082804044097000_14.2.e237032.7","doi-asserted-by":"publisher","DOI":"10.1634\/theoncologist.2010-0281"},{"key":"2025082804044097000_14.2.e237032.8","doi-asserted-by":"crossref","first-page":"2174","DOI":"10.1007\/s00595-013-0681-7","article-title":"Intra-Abdominal desmoid tumor difficult to distinguish from a gastrointestinal stromal tumor: report of two cases","volume":"44","author":"Ogawa","year":"2014","journal-title":"Surg Today"},{"key":"2025082804044097000_14.2.e237032.9","unstructured":"NCCN .
