Serous cystic neoplasms, on the contrary, present with a cuboidal or simple squamous epithelium and fibrous or hyalinized stroma without ovarian-like stroma. We present the case of a 23-year-old woman presenting with abdominal pain related to a new type of cystic pancreatic neoplasm characterized by non-mucinous pancreaticobiliary cystic epithelium and ovarian-like stroma that was surgically removed. http://pubs.sciepub.com/ajmcr/3/12/2/ajmcr-3-12-2.pdf pancreas pancreatic cysts cystadenoma
