Context Solid pseudopapillary tumor is a rare tumor of the pancreas. Solid pseudopapillary tumor is nine times more frequent in the body and tail than in the head of the pancreas. It usually does not reach a large size. The majority of patients are young females and most of them are asymptomatic. Neoplasms of the midportion of the pancreas, not suitable for enucleation, can be treated with central pancreatectomy. The central pancreatectomy is commonly proposed for tumors that do not exceed 5 cm of dimension. Case report We report a case of seventeen-years-old woman who was admitted to our institution with abdominal pain and a palpable mass in the left hypochondrial area. US, CT and RMN scan revealed a giant (>10 cm.) well-demarcated and encapsulated solid mass in the body of the pancreas, with a great amount of intralesional cystic-hemorrhagic component. The patient was treated by a variant of central pancreatectomy without splenectomy and pancreatic duct reconstruction. There was no metastatic disease in either the liver or peritoneum. The histological analysis identifies the tumor as a Solid pseudopapillary tumor of the pancreas. Fifteen years’ follow-up period showed no recurrence. Conclusions Solid pseudopapillary tumor of the pancreas behaves like a potentially malignant tumor and has good prognosis. Surgical resection is dictated by tumor location and is the treatment of choice. The increasing interest in parenchyma-sparing pancreatic surgery has found large application in treatment of Solid pseudopapillary tumor, with the aim of preserving exocrine and endocrine pancreatic function, and achieving a better quality of life after surgery. Considering the low malignant potential, the central pancreatectomy can be considered an excellent therapeutic strategy for the treatment of this type of tumor also when they have giant dimensions and are localized in the central-pancreatic portion.
