Solid Pseudopapillary Tumor of Pancreas: A Clinicopathologic Report from a Single Institution in Southern Iran

Abstract

Background: Solid pseudopapillary tumor of pancreas (SPTP) is a rare tumor of the pancreas which mostly occurs in young women. Since its first description in 1969, more than 500 cases have been reported. There have been just 2 case reports and 1 review (7 cases) from Iran. In this study, we reported our experience with 22 patients with SPT from the largest pancreaticobiliary center in Southern Iran.

Methods: During 6 years (2012-2017), 22 cases of SPTP were operated on in our center. All of these cases were recruited and after confirmation of the pathological diagnosis, clinical charts were evaluated and all the clinicopathologic findings as well as outcome of the surgery were evaluated.

Results: Among the 22 patients, 20 were female and 2 were males. The age range was 15-52 years and the tumor sizes were 3.5 to 17 cm. All of the tumors had preoperative diagnosis by imaging modalities and were operated on with no complication or recurrences. Just one case showed liver metastasis. All of the patients with SPTP in this study were alive and in good condition.

Conclusion: SPTP is not very rare in our center. In young patients presenting with pancreatic mass, especially in female patients, one of the most important diagnoses is SPTP. Conservative surgery and tumor excision is satisfactory and patients show excellent prognosis even after liver metastasis.
