Background: Most primary malignant pancreatic neoplasms are of ductal origin however non-pancreatic tumors rarely metastasize to the pancreas. Because of their radiologic appearance and sometimes misleading cytology these cancers may simulate primary pancreatic tumors leading to erroneous diagnoses and delayed/inappropriate management. We present our multi-institutional experience with secondary pancreatic tumors diagnosed exclusively by fine needle aspiration (FNA) with/without the use of immunocytochemistry (ICC).
Design: A retrospective review of the pathology departments' archives from December 1988-April 2005 (Emory) and October 2008-June 2012 (Moffitt) yielded 38 cases fitting the criteria for secondary non-hematopoietic pancreatic malignancies. Demographic, clinical, cytologic and diagnostic data were collected.
Results: Patient demographics are summarized in Table 1.
