What are immature teratomas?
What are immature teratomas?
A type of germ cell tumor that is often made up of several different types of tissue, such as hair, muscle, and bone. Immature teratomas have cells that look very different from normal cells under a microscope. They are usually malignant (cancer) and may spread to other parts of the body.
What is the difference between mature and immature teratoma?
Mature teratomas are benign tumors, which are most often composed of derivatives of two or three germ cell layers. Only in rare cases is the transition into a malignant tumor observed (most often squamous cell carcinoma). In contrast, immature teratomas are malignant ovarian tumors.
What the difference between mature cystic teratoma and immature cystic teratoma?
The morphologic features of the tumors differ in that mature cystic teratomas (dermoid cysts) are predominantly cystic, whereas immature teratomas are predominantly solid with small foci of fat.
Are all immature teratomas malignant?
Immature teratomas of the ovary contain elements derived from the three germ layers. However, unlike mature cystic teratomas, immature teratomas contain embryonal tissues. These tumors account for over 20% of malignant germ cell tumors.
What causes immature teratoma?
Teratomas result from a complication in the body’s growth process, involving the way that your cells differentiate and specialize. Teratomas arise in your body’s germ cells, which are produced very early in the development of the fetus. Some of these primitive germ cells become your sperm- and egg-producing cells.

Why is immature teratoma malignant?
An immature teratoma is a teratoma that contains anaplastic immature elements, and is often synonymous with malignant teratoma. A teratoma is a tumor of germ cell origin, containing tissues from more than one germ cell line, It can be ovarian or testicular in its origin….

How fast do immature teratomas grow?
Growing teratomas have a rapid expansion rate, with a median linear growth of 0.5 to 0.7 cm/month and volume increase of 9.2 to 12.9 cm3/month. While from the results of our study, the tumor growth was 0.94 cm/month (range 0.3–4.3 cm/month, n = 21) (Table 1 ).
Can immature teratoma be cured?
Immature ovarian teratomas are usually found in girls up to their early 20s. Even if these teratomas are diagnosed at an advanced stage, most cases are cured by a combination of surgery and chemotherapy.
How do you treat immature teratoma?
Treatment for an immature teratoma includes both surgery and chemotherapy, Patients with stage Ia grade 1 immature teratoma are usually treated with surgery alone because the prognosis is excellent. When the grade of the tumor advances to 2 or 3, or the stage goes beyond Ia, chemotherapy is usually recommended.
Is immature teratoma curable?
Fortunately, immature teratoma is a potentially curable condition as most cases exhibit excellent sensitivity to chemotherapy. This provides physicians with a significant chance of preserving fertility, even in patients with advanced stages of disease. Furthermore, most of the patients are diagnosed at an early stage.
How is immature teratoma treated?
Bagaimana Kata teratoma bisa digunakan?
