Solid pseudopapillary tumour of pancreas: a report of 5 cases.

A solid pseudopapillary tumour of the pancreas (SPT) is a rare neoplasm accounting for less than 2% of exocrine pancreatic neoplasms. SPT occurs in adolescent young females and is mostly benign. It is a low-grade malignant tumour that may evolve years before symptoms start and has a favourable prognosis. In this report we present five cases (four females, one male, aged 16, 45, 23, 17 and 55 years, respectively) of SPT localised in the pancreas, and discuss the clinical, imaging and histologic findings with a review of the literature. We retrospectively reviewed these five patients with SPT who underwent surgical resection in our hospital with a definitive histologic diagnosis of SPT.
