Mucinous cystadenoma arising from a pancreatic heterotopia

Mucinous pancreatic cystadenoma (MCA) is a premalignant lesion usually located in the body and tail of the pancreas, characteristically in females in their fifties and sixties. The definitive diagnosis relies on the presence of columnar mucin-producing epithelium and ovarian-type stroma. MCA arising from a pancreatic heterotopia (PH) has been rarely reported.
