What are the causes of ovarian teratomas? Urgent .

Ovarian teratoma.

Among the various types of ovarian tumors, there is a type of tumor that contains hair, teeth, bones and oil, which we call ovarian teratomas.

Ovarian teratoma is a common type of ovarian germ cell tumor, which is not evolved after a woman is pregnant with a freak, but is caused by the abnormal proliferation of germ cells, which is a tumor that grows in the ovarian tissue and is formed by the abnormal proliferation and aggregation of germ cells. Because germ cells contain three tissue components: human ectoderm, mesoderm and endoderm, there will be ectodermal tissues such as hair, oil, **, teeth, bone fragments, etc., and may also contain mesoderm or endodermal tissues such as muscle, gastrointestinal, and thyroid tissues.

There are several types of ovarian teratocarcinoma, including mature teratocarcinoma and immature slight femoral tumor. Of these, 97 are cystic mature teratomas, also known as dermoid cysts. Dermoid cysts are one of the most common species, accounting for 10 20 of all ovarian tumors and 85 97 of germ cell tumors.

Because it is not related to pregnancy, ovarian teratomas can occur at any age, and can occur in newborns, adolescents, middle-aged or elderly people, but 80 90 are 20 40 years old women in the reproductive period, accounting for about 1 4 1 3 of ovarian tumor patients.

Ovarian cystic mature teratomas are generally medium-sized, mostly on one side, 12 on both sides, round or oval in appearance, contained by a smooth capsule, with tough cyst walls, mostly unilocular, and the most common hair masses and oil in the cyst cavity are also often teeth and bone fragments. These tissues are differentiated and mature, so the tumors are mostly benign and about 2 malignant transformations.

A very small number of immature teratomas belong to malignant tumors, which are malignant germ cell tumors with the potential for metastasis. Tumors are mostly solid and may have cystic areas. Intratumoral tissues are not like normal tissues, and the cells are not well differentiated and have the characteristics of metastasis, erosion, and implantation.

It is more common in adolescents and children.

Generally speaking, the prognosis of immature teratoma is poor, and surgery cannot guarantee the complete and clean elimination of it, and there is a risk of **. The prognosis of benign teratoma is better, the probability of benign malignant transformation is only 2%-3%, does not affect ovarian function, menstruation is normal after surgery, the pregnancy rate is normal, and there is no problem.

You can also do tumor anti-cancer testing, such as pathology tests, you should apply for frozen sections to avoid the occurrence of secondary surgery.

2. After surgery, pregnancy can be achieved as long as normal ovarian function is restored. After the diagnosis of teratoma, surgery is advisable as soon as possible.

3. Teratoma is indeed divided into benign and malignant, but malignant teratoma is different from other ovarian malignant tumors, teratoma is formed by another embryo in the development of fetal embryo, and does not belong to the patient's own tissue, benign and malignant does not represent the nature of the patient's own ovarian tissue, as long as the operation is fine and skilled, it will be able to completely isolate the teratoma and retain the patient's own ovarian tissue, so no matter whether the teratoma is benign or malignant, it is not necessary to remove the ovaries. Laparoscopic surgery has a wide field of view and magnification, and the ovary where the teratoma is located is put into a plastic bag, which can completely remove the teratoma tissue without polluting the abdominal cavity, and at the same time facilitate the exploration of the contralateral ovary (more than 50% of teratomas are bilateral sequential onset) Therefore, teratoma surgery does not need to open the abdomen. On the surgical consent form, if there is a possibility of laparotomy or malignant teratoma requiring ovarian removal, do not sign it, which means that the hospital is not skilled in laparoscopic technology and does not have sufficient understanding of malignant teratoma.

Once the ovaries are removed, the patient quickly enters menopause, and there is no salvage. It should fall into the category of excessive**.

Hehe! Supplement: Ovarian cystic teratoma, also known as dermoid cyst, occurs in germ cells and is one of the most common ovarian tumors, accounting for more than 95% of all ovarian teratomas.

Tumors are usually 5 to 6 cm in diameter, round, smooth in surface, and often unilocular. Can occur at any age, but in young women of childbearing age 80 to 90, it does not affect menstruation and pregnancy.

Pelvic inflammatory disease should not be associated with teratoma, and chronic pelvic inflammatory disease is mainly manifested by uterorectal effusion or hydrosalpinx. Symptoms are more typical.

Ovarian teratoma is a common ovarian nest germ cell tumor. Ovarian teratomas are mainly pelvic masses, and some patients experience acute abdominal pain due to ruptured, torsional, or bleeding tumors. Most ovarian teratomas are benign mature teratomas, and only a small number are malignant teratomas.

Ovarian teratomas are usually made up of 2-3 germ layers. According to the histopathological type, it can be divided into mature teratoma, immature teratoma and ovarian goiter. The most common of mature teratomas is mature cystic teratomas, also known as dermoid cysts.

Mature cystic ovarian teratoma has a smooth surface and intact capsule, with a diameter of about 10 cm. The sac contains sebum and hair, and sometimes the scolices made up of teeth, bones, and scalp are visible, with the scolices protruding into the cavity. Ovarian teratomas containing neurological components are classified as immature teratomas, and immature ovarian teratomas vary in degree of differentiation and have mixed components ranging from carcinoma to sarcoma.
