- Ovarian serous cystadenoma
Ovarian serous cystadenoma Classification and external resources ICD-O: 8442/1 MeSH D018293
Ovarian serous cystadenoma, also (less precisely) known as serous cystadenoma, is a very common benign ovarian tumour.
It has a very superficial resemblance to the most common type of ovarian cancer (serous carcinoma of the ovary) under the microscope; however, (1) it is virtually impossible to mix-up with its malignant counterpart (serous carcinoma), and (2) does not share genetic traits of indeterminate serous tumours, so called serous borderline tumours, that may transform into serous carcinoma.
Serous cystadenomas (of the ovary) are not related to serous cystadenomas of the pancreas, i.e. the presence of an ovarian or pancreatic one does not suggest an increased risk for the other one.
Serous cystadenomas are diagnosed by histomorphologic examination, by pathologists. Grossly, they are, usually, unilocular cysts that contain clear, straw-coloured fluid. Microscopically, the cyst lining consists of a simple epithelium with cilia that may be columnar or flat.
