Solid-pseudipapillary pancreatic tumor is an uncommon pancreatic neoplasm of unknown origin that occurs especially in young women. It is a low grade malignancy that rarely metastatizes and generally the prognosis is excellent. Patients are generally asymptomatic with normal liver and pancreatic function and tumor markers generally are negative. It is characterized by a mixed structure with both solid and cystic areas with calcification especially in the cystic areas, that can be seen at CT scan. In some cases MRI and biopsy may be useful to obtain a diagnoses before surgery. The macroscopic pseudopapillary structure with solid and cystic areas with fibrovascular core it is considered. diagnostic. The treatment consisted in an adequate surgical resection and generally it is curative. We present the case of a young 28 years old woman with an asymptomatic pancreatic mass, with solid and cystic areas and calcification at pre-operatory CT. She has no limphoadenopaty and metastases at staging CT scan. She was performed a distal pancreatectomy with splenectomy with the istologic diagnosis of solid-pseudopapillary tumor with the positivity of NSE and CD56 and no nodal metastases. 7 months after surgery she performed a normal life and the follow up examinations are negative for tumor recurrence.
