Ovarian cystadenocarcinoma

Ovarian cystadenoma, translated into English as cystadenoma of ovary. It is a type of uterine and ovarian tumor. A cystadenoma is a tumor in the uterine and ovarian ducts in which secretions are stored and enlarged in a cystic manner. Because the disease occurs in the uterus and ovaries, it is called ovarian cystadenoma. Cystadenomas have chambers of varying sizes due to the proliferation of glandular epithelial cells lining the lumen. The contents may include various substances such as plasma, mucus, pseudomucus, collagen fibers, etc. It is more common in the uterus and ovaries, but is also common in the breast, kidney function, pancreas, and liver.

Causes of ovarian cystadenoma

Cystadenoma: Due to the deposition of secretions in the glandular ducts in cystadenoma, the glandular cavities gradually expand and merge with each other, and cystic cavities of varying sizes can be seen by the human eye. Cystadenomas often occur in the uterus and ovaries, and are occasionally seen in thyroid cysts and pancreas. There are two main types of ovarian cystadenoma: one is that the glandular epithelium grows in the cystic cavity in a papillary manner and secretes plasma, so it is called serous papillary cystadenoma; the other secretes mucin, is often multilocular, has a smooth cystic wall, and has small papillary hyperplasia, which is called mucinous cystadenoma. Among them, serous papillary cystadenoma is prone to deterioration and transformation into serous cystadenocarcinoma.

Ovarian cystadenoma Serous cystadenoma

It accounts for about 25% of benign tumors of the uterus and ovaries and is more common in patients aged 30 to 40 years old. Mostly on one side. It is grayish white in appearance, with a smooth surface, mostly unilocular, with a thin cyst wall. The cyst contains light yellow clear transparent fluid. In some case records, papillary protrusions can be seen in the inner cavity, which are clustered or diffusely scattered, and are called papillary serous cystadenoma. The papilla can protrude the cyst wall, spread and grow on the surface of the cyst, and even invade adjacent organs. If accompanied by ascites, deterioration has mostly occurred. [1]

Common location of ovarian cystadenoma

Cystadenomas are common in endocrine glands such as the breast, pituitary gland, thyroid cysts, uterus and ovaries, as well as the stomach, intestines, and liver. Growth retardation and the development of localized masses with cystic or papillary surfaces. It is composed of cubic epithelial cells or columnar squamous epithelial cells that are similar to normal glandular cells. The somatic cells are also arranged neatly, with a clear boundary between their original membrane and the surrounding connective tissue, but the lack of metabolic tubes or abnormal metabolism indicates some heterogeneity in structure and function. The stroma of cystadenomas is composed of connective tissue containing blood vessels. Many tumors are associated with marked connective tissue hyperplasia (fibro-adenoma). Sometimes there is a malignant cystadenoma, which is actually a type of cancer. The formation, growth and development of cystadenoma are mostly controlled by endocrine, nervous and other body regulatory organizations. In this sense, some experts and scholars believe that cystadenoma is only a physiological tissue proliferation rather than a real tumor.
