AB Background: Solitary fibrous tumors (SFTs) are rare biological entities described mainly in the pleura. To date, in the pancreas, only 14 cases have been reported in the English literature. Case Report: A 52-year-old male was diagnosed incidentally with a suspected neuroendocrine tumor (NET) of the pancreas. He underwent pancreatic enucleation of the mass, which, at final pathology, showed spindle cell proliferation set in a collagenous background and featuring the presence of hemangiopericytoma-like blood. Immunohistochemistry showed cytoplasmic expression of CD34 and nuclear expression of STAT6. As mitotic activity was of 1 mitoses/10 high-power fields (HPFs) a diagnosis of conventional SFT was made. The patient was discharged without major complications and is alive and free of disease after 24 months. Conclusion: SFTs of pancreas are rare tumors, often mimicking pancreatic NET.
