Definition : A malignant cystic or semicystic neoplasm. It often occurs in the ovary and usually
bilaterally. The external surface is usually covered with papillary excrescences.
Microscopically, the papillary patterns are predominantly epithelial overgrowths with
differentiated and undifferentiated papillary serous cystadenocarcinoma cells. Psammoma
bodies may be present. The tumor generally adheres to surrounding structures and produces
ascites. (From Hughes, Obstetric-Gynecologic Terminology, 1972, p185) [MeSH];
