Solid Pseudopapillary Tumour (SPPT) is a distinctive tumour of low malignant potential with a striking and unexplained predilection for adolescent girls and young women. Hence it is important to distinguish this rare tumour from other pancreatic tumours with similar cytomorphologic features because an accurate preoperative diagnosis is highly desirable since these patients can have long survival with adequate surgery. We report a case of the rare SPPT of the pancreas in a young girl who presented with nonspecific pain in the abdomen. Radiological investigations revealed a solid cystic mass in relation to the uncinate process of pancreas and third part of duodenum. The mass was diagnosed to be a solid pseudopapillary neoplasm of pancreas on ultrasound guided FNAC. Surgical removal of the pancreatic tumour and detailed histologic study confirmed the cytologic diagnosis. We present this case because, to date, there are few case reports on the cytological diagnosis of this tumour, about 60 cases, diagnosed by Fine-Needle Aspiration Cytology (FNAC) are reported in the literature. With widespread availability of high-quality imaging systems and a better understanding of its pathology, the number of cases reported in the literature has been steadily increasing in recent years. In our case, the cytological diagnosis was done even before the detailed imaging findings were available, the cytological features of this tumour are highly characteristic and it is possible to differentiate it from other pancreatic tumours with relative ease.
