EUS‐guided FNA cytology of pancreatic neuroendocrine tumour (Pan<scp>NET</scp>): a retrospective study of 132 cases over an 18‐year period in a single institution

Abstract

Overall, 54 of the 70 histologically confirmed PanNET cases (77%) were correctly diagnosed by preoperative FNA as PanNET. FNA cases designated as no atypical cells identified and unsatisfactory (7/132, 5%) were attributable to sampling error. Diagnostic pitfalls in our study mainly included PDA, SPT and chronic pancreatitis.
