BELTRAN S, Marcelo A et al. Solid-pseudopapillary tumor of pancreas. Rev Chil Cir [online]. 2015, vol.67, n.3, pp.285-291. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262015000300008.

Introduction: The solid-pseudopapillary tumor of pancreas (STP) is a low-grade malignant neoplasm. In Chile, 21 cases have been reported since 2008, most of them treated in Santiago. The present series contributes to the national case-load and has the purpose to describe the experience with this uncommon neoplasm in the IV Region. Patients and Methods: From January 2004 to March 2014, a total of 38 benign and malignant pancreatic neoplasms have been informed in the data-base of our Regional Pathology Service. We selected the biopsies informed as STP and 5 cases (13%) were found. The clinical records of these patients were retrospectively reviewed. The results were reported using descriptive statistics with central tendency measures and dispersion. Results: Most patients were women with a mean age of 44.8 years. All patients were studied with either abdominal ultrasound; computed tomography or magnetic resonance. In 2 patients the STP was located in the pancreatic tail, and they were submitted to distal pancreatectomy. The other 3 patients had the STP in the pancreatic head and were resolved by pancreatoduodenectomy. All tumors were confirmed by immunohistochemistry. Late follow-up showed malignant behavior in 1 patient while the other 4 patients are currently free of disease. Conclusions: The general characteristics of STP in the IV Region are similar to what is currently known. They present a high incidence compared with the habitually published incidence.
