Abstract:

Ovarian teratoma is a type of germ cell tumour. Germ cell tumours are cancers that begin in egg cells in women or sperm cells in men. There are two main types of ovarian teratoma

* Mature teratoma, which is benign
* Immature teratoma, which is cancerous

Background: The most common type of ovarian germ cell tumor is the teratoma. Thyroid tissue, both benign and malignant, may be a component of an ovarian teratoma. Here we review this topic and illustrate major features by presenting multimodal management of a patient with BRAF-positive disseminated follicular thyroid cancer arising in an ovarian teratoma.

Conclusions: Aggressive multimodal management appears to be the most promising approach for malignant thyroid tissue arising in ovarian teratomas.

Is adjuvant chemotherapy indicated in stage I pure immature ovarian teratoma (IT)? A multicentre Italian trial in ovarian cancer

CONCLUSIONS.: Our study suggests that chemotherapy may be withheld for primary therapy and utilized only for recurrence.
