Solid Pseudopapillary Tumor of the Pancreas in a Patient With Sarcoidosis: A Rare Combination

Sarcoidosis is a chronic granulomatous disease that is characterized by the formation of non-caseating granulomas, predominantly involving the lung and lymph nodes. Over the years, sarcoidosis has been associated with a high risk of malignancy. Solid pseudopapillary tumor of the pancreas is an uncommon pancreatic tumor with a 15% malignant potential. Ours is an interesting case of a 34-year-old patient who was found to have a pancreatic mass and incidental mediastinal lymphadenopathy on imaging, initially raising concern for metastatic pancreatic cancer. However, she was later diagnosed to have an isolated solid pseudopapillary tumor of the pancreas in association with concurrent sarcoidosis.
