A mucinous cystic neoplasm is an abnormal and excessive growth of tissue (neoplasm) that typically has elements of mucin and one or more cysts. By location, they include:
Pancreatic mucinous cystic neoplasm. These lesions are benign, though there is a high rate of progression to cancer. As such, surgery should be pursued when feasible. The rate of malignancy present in MCN is about 10 percent.[1] If resection is performed before invasive malignancy develops, prognosis is excellent. The extent of invasion is the single most important prognostic factor in predicting survival.[2]
Mucinous cystic neoplasms of the liver are a type of liver cancer in which tissue similar to the stroma of ovary occurs.[3]
