Cystadenocarcinoma is a malignant form of a cystadenoma and is a malignant neoplasm derived from glandular epithelium in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness and local extension and metastases occur. Cystadenocarcinomas develop frequently in the ovaries where pseudomucinous and serous types are recognized.
