| cystadenocarcinoma, serous | A malignant cystic or saemicystic 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 tumour generally adheres to surrounding structures and produces ascites. (12 Dec 1998) |

| cystadenoma, serous | A cystic tumour of the ovary, containing thin, clear, yellow serous fluid and varying amounts of solid tissue, with a malignant potential several times greater than that of mucinous cystadenoma (cystadenoma, mucinous). It can be unilocular, parvilocular, or multilocular. It is often bilateral and papillary. The cysts may vary greatly in size. (12 Dec 1998) |
