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.
, 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.

Diagnosis
Serous cystadenomas are diagnosed by histomorphologic examination, by pathologists. GrosslyGross pathology
Gross pathology refers to macroscopic manifestations of disease in organs, tissues, and body cavities. The term is commonly used by anatomical pathologists to refer to diagnostically useful findings made during the gross examination portion of surgical specimen processing or an autopsy.It's vital...
