Intraductal papillary mucinous neoplasia--a challenging diagnosis in a patient with paraneoplastic rheumatoid...

Intraductal papillary mucinous neoplasias (IPMNs) of the pancreas are potentially malignant tumors, and associated also with extrapancreatic carcinomas. We present the case of a 80 year old man with IPMN and late onset of rheumatoid arthritis. The particularity of this case is the discordance between the clinical picture and the imaging worrisome features, together with the surgery-requiring mixed-type of IPMN, despite the late possible paraneoplastic onset of rheumatoid arthritis.
