Questions about 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. So it's not uncommon to grow there, 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 of compounding.

Teratomas are a variety of tumors.

Originating from potentially multifunctional blasts, most of them are benign, but the malignant tendency increases with age. The site of occurrence is related to the anterior midline axis or paramidline area of the embryonic body cavity, and is more common in the sacrococcygeal, mediastinum, retroperitoneum, and gonadal sites.

Benign teratomas are mainly surgically removed.

The surgery for malignant teratoma is different from that for benign tumors, and it is necessary to go to a regular cancer hospital. After the operation, a further ** plan was formulated according to the results of pathological examination.

Good luck!
