Mature teratomas contain lipids, hair, and even bone and other tissue structures within the tumor cavity. The main reason for this is that teratomas are composed of cells from multiple embryonic layers. These embryonic layer cells can develop in different directions, further developing into tissues such as hair, lipids, or bones. Therefore, during surgical procedures, it is common to find hair within the teratoma.

Teratoma Benign and Malignant Differences

Teratoma refers to a common type of germ cell tumor, which can be classified into mature teratomas and immature teratomas. Mature teratomas are benign tumors, accounting for 10%-20% of ovarian tumors. They can occur at any age but are more common between the ages of 20 and 40. Most are unilateral, of moderate size, and usually have a single compartment filled with sebum and hair; sometimes teeth and bone can also be found. Immature teratomas, on the other hand, are malignant tumors, making up 1%-3% of ovarian teratomas. These are more frequent in younger patients, with an average age of 11 to 19 years. The ovaries are predominantly solid but may include cystic areas, primarily consisting of primitive neural tissue. The malignancy level of the ovary depends on the proportion of immature tissue, the degree of differentiation, and the content of neuroepithelial tissue.

Can a teratoma disappear with medication?

Ovarian teratomas cannot be treated with medication. Ovarian teratomas are the most common type of germ cell tumor and are categorized into mature and immature teratomas. Mature teratomas, also known as dermoid cysts, are mostly benign tumors. These cysts generally have a single chamber filled with sebum and hair, and sometimes teeth and bone material can also be found inside. On the other hand, immature teratomas are malignant tumors, making up 1%-3% of ovarian teratomas, commonly seen in younger patients with an average age between 11 and 19 years. Thus, it is crucial to seek prompt medical evaluation upon detection of an ovarian teratoma to determine the size of the cyst and, if necessary, pursue surgical treatment, as medication will not resolve the issue.

Is teratoma a twin?

Teratomas have no specific correlation with pregnancy status. Teratomas are a type of ovarian cyst and are tumors of the ovaries. Generally, when teratomas are diagnosed clinically, hospitalization and surgery are required for treatment. Teratomas are not connected to twin pregnancies. Teratomas are relatively common in clinical settings, and the diagnosis needs to be confirmed by postoperative pathology. Teratomas can be categorized into benign and malignant types, each requiring different treatments.

The difference between ovarian teratoma and cysts

Ovarian teratomas are a type of ovarian cyst, and clinically, ovarian teratomas are not differentiated from ovarian cysts. Because ovarian teratomas and ovarian cysts are not diseases of the same category; teratomas are one type among the various classifications of ovarian cysts. Therefore, there is no difference between ovarian teratomas and ovarian cysts, and clinically, they may refer to the same category of disease.

Does teratoma affect the fetus?

Teratoma is a common benign ovarian tumor in women, and most teratomas do not affect the fetus. Since the majority of teratomas are smaller than 5cm, even under the stimulation of pregnancy, teratomas generally do not grow significantly large, and it is generally considered that small teratomas do not affect the fetus. However, if the teratoma is very large, more than 8cm, there is a risk of rupture and infection during pregnancy, which could potentially affect the fetus. For large teratomas during pregnancy, enhanced monitoring is necessary to avoid rupture and infection, in order to protect the fetus.
