Pancreatic Collision Tumor of Desmoid-Type Fibromatosis and Mucinous Cystic Neoplasm: A Case Report

ABSTRACT

Pancreatic collision tumors are rare neoplasm, and cases consisting of ductal adenocarcinoma with a neuroendocrine tumor, intraductal papillary mucinous neoplasm with a neuroendocrine tumor, and solid pseudopapillary neoplasm with a neuroendocrine tumor have been reported. We report a case of a rapidly growing pancreatic collision tumor consisting of desmoidtype fibromatosis and mucinous cystic neoplasm in a 30-year-old pregnant female. To the best of our knowledge, this is the first reported case of a pancreatic collision tumor consisting of desmoid-type fibromatosis and mucinous cystic neoplasm.
