Solid Pseudopapillary Neoplasm of Pancreas; a Case Series and Review Literature

Abstract

BACKGROUND:

Information regarding solid pseudopapillary neoplasm (SPN) of the pancreas is limited in Iran. We aimed to review the clinicocytopathological features and follow-up of patients with SPN of pancreas who were diagnosed in a single center in Iran.

METHODS:

Seven patients with SPN of the pancreas were diagnosed during January 2010 to March 2015 at the Digestive Disease Research Institute of Tehran University of Medical Sciences. The patients were reviewed prospectively.

RESULTS:

Six out of the 7 patients were female and the mean age of all the patients was 29.4 years ranging from 15 to 61 years. The most common clinical presentation was nonspecific abdominal pain (N=6). The tumors were located mostly in head and neck of the pancreas. SPN was diagnosed in all patients by fine needle aspiration through endosonography (EUS-FNA). All patients underwent surgery. Histological findings of surgical tissues were consistent with EUS-FNA. The postoperative follow-up period of about 14 months was uneventful.

CONCLUSION:

SPN of the pancreas is a rare pancreatic tumor which affects primarily young women. EUS-guided FNA could play an important role in preoperative diagnosis of SPN of the pancreas.
