Solid pseudopapillary tumour of the pancreas is a rare tumour of low malignant potential occurring predominantly in young females. Its incidence has been increasing due to advanced imaging modalities. As this tumour offers a good prognosis, it is important to make a proper diagnosis to offer better treatment and reduce morbidity.
MATERIALS AND METHODS
This is a prospective study for a period of 2 years (From May 2014 to April 2016). Of the 52 pancreatic specimens we received after surgery, 9 cases had a prior radiological diagnosis of solid pseudopapillary tumour of the pancreas. The clinical and histo-pathological characteristics of SPT were studied along with review of literature. Whipple resection specimens which were radiologically diagnosed as adenocarcinoma of the periampullary region were excluded.
Nine cases were reported radiologically as papillary neoplasm of pancreas. On histopathology, 8 of them were confirmed as solid pseudopapillary tumours of the pancreas. One was a case of serous cystadenoma and other one was pancreatic neuroendocrine tumour. One case which was suspected as pancreatic endocrine tumour radiologically was diagnosed as SPT.
SPT typically is limited to the pancreas at the time of diagnosis, and even with metastasis, an extended complete surgical excision offers good prognosis. Hence, it is important to distinguish it from other tumours of similar morphology. In this study, we discuss the process of establishing the diagnosis accurately of SPN in young patients presenting with pancreatic mass.
