A case of solid-pseudopapillary neoplasm in an elderly male diagnosed by EUS-FNA

Abstract

A 69-year-old male was referred to our hospital because of mass detected in the pancreatic head. Contrast-enhanced CT scan showed a pancreatic head tumor, 30mm in diameter, which was hypo dense in early phase and hyper dense in delayed phase with central calcification, and cystic. An endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed and the histological diagnosis of solid-pseudopapillary neoplasm (SPN) was confirmed by H&E and immunohistological stain. A pancreatoduodenectomy was therefore performed. SPN is relatively rare pancreatic tumor appearing most commonly in young females and calcification is often found in the margins of the tumor. Male cases of SPN are very rare and sometimes present different clinical findings from female cases. Therefore EUS-FNA is useful for the differential diagnosis of pancreatic tumor in such cases.
