title: Malignant teratoma of the thyroid: case report.
abstract: Teratomas in the neck are rare neoplasms. Most of them occur in infants less than 1 year and are benign. In contrast, thyroid teratomas in adults are malignant and have fatal outcomes because of spread of tumor refractory to treatment. We report a case of a primary thyroid malignant teratoma in a 37-year-old woman. She was treated successfully with a combination of surgery, postoperative cis-platinum-based chemotherapy, and radiation therapy to the neck. Although the time of follow-up is short (24 months), we attribute her successful outcome to the use of this intensive therapeutic approach.
