Background : Solid pseudopapillary tumor of the pancreas (SPTP) is a rare pancreatic neoplasm. The aim of this study was to discuss the clinical presentation, management, and outcome of patients with this kind of tumor. Materials and Methods : A retrospective review was performed in 6 patients with SPTP surgically treated between January 2004 and September 2011 in our hospital. Results : All the 6 patients were female. The mean age of the patients was 39 years (range, 18 to 67 years). The main clinical presentation was abdominal pain or discomfort, however a third of the patients were asymptomatic. The mean size of the tumor was 9.7 cm (range, 2.5 to 18 cm). Three tumors had a well defined capsule, 3 tumors extended in the pancreas. Four of the 6 tumors had a cystic component, and calcifications were observed in one tumor. No lymph node involvement, no lymphatic invasion and no nerve invasion were observed. One tumor showed an infiltration of the splenic vein, and another patient had a liver metastasis with complete resection. Distal pancreatectomy (n = 3), local resection (n = 1), cephalic duodenopancreatectomy (n = 1), and distal pancreatectomy associated with a right hepatectomy (n = 1) were performed. The main postoperative complication in the short term was bleeding (n = 1), and long term the development of an insulin-requiring diabetes (n = 2). No patient received adjuvant therapy. Overall mortality rate was 0%. All patients were still alive without recurrent disease with a median follow up of 36.2 months. Conclusion : Patients with SPTP have an excellent prognosis after its complete removal, even if it is a minimized resection.
