Solid Pseudopapillary Tumour of Extrapancreatic Origin Presenting as Mesenteric Cystic Mass: A Diagnostic Dilemma

Solid Pseudopapillary Tumour (SPT) is a rare and distinctive pancreatic exocrine neoplasm. Even Rarely, such primary SPT may originate from ectopic pancreatic tissues. We are hereby presenting one such unique case, where a 50-year-old female presented with pain and a mid-abdominal lump. Radiology revealed a well-defined outline located adjacent to the tail of pancreas. The excised mass was 19×14×7cm in dimension having zones of haemorrhage, necrosis and cystic spaces filled with necrotic debris. Microscopic examination confirmed the diagnosis of SPT. SPT originating in extrapancreatic location may mimic an ovarian cystic tumours or mesenteric cysts, its proper identification is crucial.
