Dermoid ovarian cyst: causes of occurrence - more information!

A dermoid cyst, or mature teratoma, of the ovary is a non-hormonal-active tumor that originates from embryonic cells and is detected at any age. It is also called a dermoid. The cyst is a bag of dense connective tissue. Inside it is a mucus-like content that includes inclusions from various tissues: nervous, fatty, epithelial, and also hair, nails, teeth, bones, etc.

The dermoid is located more often on the right, which is determined by the peculiarities of the anatomy and physiology of the rightovary, which is more active and blood-supplying. Rarely found bilateral form.

If the formation is small, it usually does not affect the condition of the female body and is detected accidentally during ultrasound of the small pelvis.

cyst. But a dermoid cyst can grow, reaching a large size, press on adjacent organs, causing a violation of urination and defecation, pain.

Pain syndrome also occurs when a ruptured, inflamed cyst or twisted its legs. The last complication leads to peritonitis. In rare cases, a cyst degenerates into a malignant tumor.

Why mature ovarian teratoma

begins to grow It is believed that the cause of dermoid development in the ovary are hormonal changes. This conclusion was made on the basis that the dermoid cyst is more often diagnosed during periods of endocrine changes in the female body:

• in girls at the puberty stage;
• in pregnant women;
• in postmenopause.

Sometimes there is another cause - trauma in the abdomen.

But both etiological factors are not considered true. It will be more correct to say that endocrine changes and trauma only initiate the growth of the cyst, and not its occurrence.

The true causes of dermoid development in the ovary

The etiology of teratoma development in the ovary has not been fully determined.

Scientists agree that the dermoid cyst is a congenital pathology, that is, that has arisen during the pre-natal development of the girl, which is likely to contribute to various factors affecting the pregnant woman, especially at the very beginning of gestation:

• physical effects, for example, extreme temperatures, radiation and so on;
• chemical factors( drugs, toxins);
• biological( infection).

A special role is played by chromosomal abnormalities, which can occur both in the process of embryogenesis and in the reproductive cells before fertilization.

Please note! It is at the stage of the laying of organs that takes place at the beginning of the gestational period, that pregnant women need to be protected especially. In addition, following a healthy lifestyle, the expectant mother reduces the risk of anomalies not only in her children, but also in her grandchildren, since the egg stock is formed in the girl even before the birth.

However, theories about the pathway of tumor development are different. Among them, there are 3 versions.

Source of teratom - primary germ cells

Dermoid cysts are formed from the primary germ cells( AUC) of the embryo, which during the intrauterine development pass the stage of migration for the further formation of the genital organs. As a result of any violations of AUC give rise to a tumor containing elements from three germinal sheets. This theory explains the preferential localization of teratoma in the ovaries in women and men's testicles.

Failures in the differentiation of embryonic sheets

At the initial stage of development, the embryo consists of three embryonic sheets.

Germinal leaf	What is formed from it
Ectoderm( external)	nervous system, some parts of the sense organs, the skin and its derivatives, enamel of the teeth, the epithelium of the oral cavity.
Mesoderm( medium)	dermis( layer in the skin), heart membrane, musculoskeletal system, heart and blood vessels, pleura, smooth muscles( contractile apparatus of internal organs), blood, lymph, connective tissue.
Endoderm( internal)	epithelium of the gastrointestinal tract, liver, digestive glands including pancreatic, parathyroid and thyroid glands, pituitary elements.

In the process of embryogenesis, elements move relative to each other. In addition, they have mutual influence, which determines the further differentiation.

However, due to chromosomal abnormalities or adverse external influences, there is a disruption in the movement of portions of the three embryonic strata and their development. As a result, groups of cells of one layer turn out to be uncharacteristic for them, for example, ectodermal areas - in the ovary. It is this process that ultimately leads to the formation of a dermoid cyst.

Underdeveloped twin

There is also another popular and interesting opinion. This is the so-called version of the Embryo in the Embryo.

According to her, the teratoma is the result of a multiple pregnancy, when a strong fetus absorbs a weaker twin, which often has chromosomal abnormalities.

Thus, all the described theories explain that the laying of the dermoid occurs during the period of intrauterine development. Already after the action of trigger mechanisms, for example, hormonal changes, the dermoid cyst begins to grow, which leads to the appearance of unpleasant symptoms.

Important! The origin of mature ovarian teratomas is another evidence of the importance of taking precautions by a woman bearing a baby. Since any impact can have consequences that can manifest at any moment in the life of the born person.
