Case of an abnormal procalcitonin‐producing metastatic pancreatic neuroendocrine tumor

Abstract

Abstract Procalcitonin (PCT) is widely used to diagnose a bacterial infection. An increased serum PCT can also be observed in tumors. We presented an unusual case of a metastatic PNET producing and secreting PCT. Immunohistochemistry was used to demonstrate that PCT can be secreted by PanNET.
