Abstract

PURPOSE: A solid pseudopapillary tumor (SPT) is a rare pancreatic neoplasm, with low malignant potential, which tends to occur predominantly in younger females. Most patients are diagnosed due to the abdominal pain or the large palpable abdominal mass. The treatment is surgical resection, using either enucleation or more radical procedures. Only a few cases of SPT have been reported; therefore, the purpose of this study was to evaluate the clinicopathological characteristics and prognosis after surgical resection of this rare type of tumor. METHODS: In this paper, twelve cases of SPT, treated at the Department of Surgery, Chonnam National University Hospital, between 1994 and 2003, are presented. RESULTS: 10 females, with a mean age of 32.2 years, ranging from 14 to 48, and 2 males, aged 15 and 32, were diagnosed. The tumors were large, with a mean resected diameter of 7 cm, had cystic degene rations between the solid areas, and were distributed in the head (7 cases) and the body-tail (5 cases) of the pancreas. Immunohistochemical studies were performed in 7 patients, which revealed the majority of the cases to be a-1 antitrypsin and neuron specific enolase (NSE) positive. The surgical managements of the tumors included enucleation (6 cases) or more radical procedures, such as a distal pancreatectomy (5 cases) and pancreaticoduodenectomy (1 case). There was no recurrence after the complete surgical resection. CONCLUSION: The mainstay of treatment in patient with a SPT is surgical resection, after which the prognosis was favorable.
