Solid pseudopapillary neoplasms (SPN) of the pancreas are rare tumors, occurring in 1-2% of all pancreatic neoplasms; of these 10 to 15% have an aggressive presentation. Most of the patients present disease localized to the pancreas, however, between 9-15% may present local invasion and metastasis. The clinical presentation in the vast majority of SPN is asymptomatic, even despite a large tumor size. We present a case of a 16-year-old female patient with a psedupapillary tumor of the pancreas (Frantz tumor) who was admitted due to abdominal pain and weight loss lasting 3 months.
