This case report, to the best of our knowledge, is the first report of CD simulating a pancreatic neuroendocrine tumour . The patient was a 58-year-old woman who initially presented with bilateral iritis and underwent investigation for possible systemic rheumatological disease. CT of the chest demonstrated an incidental finding of a well-demarcated retropancreatic mass. As the mass was found to enhance on DOTATATE (tetraazacyclododecanetetraacetic acid-DPhe1-Tyr3-octreotate) positron emission tomography, a diagnosis of pancreatic neuroendocrine tumour was made. The patient underwent an open distal pancreatectomy and splenectomy. Histopathological examination revealed the unexpected diagnosis of hyaline vascular CD of a lymph node posterior to the pancreas. After 2 years of follow-up, there is no evidence of disease recurrence.<\/jats:p>","DOI":"10.1136\/bcr-2021-242597","type":"journal-article","created":{"date-parts":[[2021,6,24]],"date-time":"2021-06-24T12:22:06Z","timestamp":1624537326000},"page":"e242597","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Castleman\u2019s
