They are usually associated with ulcerative colitis, Crohn's disease, previous radiotherapy, renal transplantation and AIDS. We present a 36-year-old immunocompetent man, previously well with abdominal pain, weight loss and palpable mass in the right iliac fossa. A CT scan of the abdomen showed a thickening of the terminal ileum and the caecum with characteristic aneurysmal luminal dilation. Given the patient's presentation and radiology findings, a right hemicolectomy was performed. The suspected diagnosis of NHL, which was based on the imaging findings, was confirmed at histological analysis.<\/jats:p>","DOI":"10.1136\/bcr-2013-009052","type":"journal-article","created":{"date-parts":[[2013,6,4]],"date-time":"2013-06-04T00:53:39Z","timestamp":1370307219000},"page":"bcr2013009052","source":"Crossref","is-referenced-by-count":0,"title":["Primary ileocaecal B-cell non-Hodgkin lymphoma (NHL): a rare underlying cause of right iliac fossa pain"],"prefix":"10.1136","volume":"2013","author":[{"given":"Paschalis","family":"Gavriilidis","sequence":"first","affiliation":[{"name":"Department of Pathology, Theageneio Anticancer Hospital, Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara","family":"Christoforidou","sequence":"additional","affiliation":[{"name":"Department of Pathology, Theageneio Anticancer Hospital, Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilektra","family":"Michalopoulou","sequence":"additional","affiliation":[{"name":"Department of Pathology, Theageneio Anticancer Hospital, Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasia","family":"Nikolaidou","sequence":"additional","affiliation":[{"name":"Department of Pathology, Theageneio Anticancer Hospital, Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,6,3]]},"reference":[{"key":"2025082805355026000_2013.jun03_1.bcr2013009052.1","doi-asserted-by":"crossref","first-page":"358","DOI":"10.1002\/1097-0142(19900115)65:2<358::AID-CNCR2820650230>3.0.CO;2-0","article-title":"Primary ileocecal lymphoma.
