Quick Answer: Is immature teratoma ovarian cancer?

Is an immature teratoma cancer?

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.

Is a teratoma considered cancer?

Teratomas usually occur in the ovaries in women, the testicles in men, and the tailbone in children. They may also occur in the central nervous system (brain or spinal cord), chest, or abdomen. Teratomas may be benign (not cancer) or malignant (cancer).

What happens immature teratoma?

Immature teratomas are made of tissues that resemble those found in an embryo. They are the malignant cousins of the very common mature cystic teratomas or dermoid cysts. When immature teratomas occur in combination with other germ cell tumors, they are then called “mixed germ cell tumors.”

Is immature teratoma fatal?

Extragonadal teratoma is the most common congenital tumor. The prognostic significance of the grade of immaturity and the presence of small foci of conventional yolk sac tumor (YST) in fetal and neonatal teratomas have not been determined.

How do you know if a teratoma is mature or immature?

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. Struma ovarii and carcinoid tumors are monodermal teratomas and do not demonstrate fat.

Can a mature teratoma turn into cancer?

Mature cystic teratoma (MCT) is the most common type of ovarian germ cell neoplasm, but occasionally it may undergo malignant change in any one of its elements.

Are teratoma tumors alive?

Mature teratomas are usually benign (not cancerous). But they may grow back after being surgically removed. Immature teratomas are more likely to develop into a malignant cancer.

Can a teratoma cause weight gain?

If ACTH is secreted in excess it can cause an increase in cortisol secretion, which can be associated with the symptoms this patient was experiencing, including acute weight gain and abdominal striae [2].

Do ovarian teratomas need to be removed?

Ovarian teratoma

Although malignant degeneration is quite rare, the cyst should be removed in its entirety, and if immature elements are found, the patient should undergo a standard staging procedure.

When should a teratoma be removed?

If a teratoma is diagnosed during laparoscopy or oocyte retrieval, it should be promptly removed as malignant transformation is not excluded. In this case, the embryos should be frozen for later transfer. Benign mature teratomas, commonly called dermoid tumours, make up 10-15% of all ovarian tumours.

Is immature teratoma curable?

Conclusions: Pure ovarian immature teratoma is a potentially curable disease with a unique natural history. Our data substantiate the hypothesis that low-grade and low-stage tumors do not require chemotherapy, and that a fertility-sparing surgical approach is warranted in all cases.
