Solid-pseudopapillary neoplasms of pancreas (Q94566)

A low-grade malignant neoplasm that arises from the exocrine pancreas. It is characterised by the presence of uniform cells that form solid and pseudopapillary patterns, cystic changes, and hemorrhage. Perineural invasion, vascular invasion, and invasion into surrounding tissues may be present. It usually presents as an encapsulated, solitary, and lobulated pancreatic mass. It is usually found incidentally during physical examination or it may present with abdominal discomfort and pain. It occurs predominantly in young women. Complete removal of the tumour is curative in the majority of cases.
