Diagnosed mainly in the mesentery, omentum, retroperitoneum, pelvis and lungs, IMT is extremely rare as a primary gallbladder tumour. Despite improved radiographical capabilities, differentiating the tumour from other more common causes of gallbladder neoplasms necessitates histopathological and immunohistochemistry tests. Once diagnosed, malignant potential should be taken into consideration, striving for an en bloc R0 resection and postoperative long-term follow-up with routine ancillary imaging. The authors present the case of a recurrent primary IMT of the gallbladder, after two surgical treatments, including a pancreaticoduodenectomy. Now 3 years after initial diagnoses the patient is asymptomatic, but has developed local and distant metastases and is being treated with systemic corticosteroid.<\/jats:p>","DOI":"10.1136\/bcr-2019-232861","type":"journal-article","created":{"date-parts":[[2020,2,11]],"date-time":"2020-02-11T04:15:14Z","timestamp":1581394514000},"page":"e232861","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Recurrent metastatic primary inflammatory myofibroblast tumour of the gallbladder following pancreaticoduodenectomy"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0567-0655","authenticated-orcid":false,"given":"Roi","family":"Anteby","sequence":"first","affiliation":[{"name":"Division of Surgical Oncology, Mount Sinai Hospital, New York, NY, USA"},{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brianne J","family":"Sullivan","sequence":"additional","affiliation":[{"name":"Division of Surgical Oncology, Mount Sinai Hospital, New York, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malary","family":"Mani","sequence":"additional","affiliation":[{"name":"Department of Pathology, Mount Sinai Hospital, New York, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin","family":"Golas","sequence":"additional","affiliation":[{"name":"Division of Surgical Oncology, Mount Sinai Hospital, New York, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,2,10]]},"reference":[{"key":"2025082803563018000_13.2.e232861.1","unstructured":"Coffin CM , Fletcher JA .
