A Case of Malignant Struma Ovarii / 대한산부인과학회잡지

ABSTRACT

Struma ovarii consists of thyroid tissue derived from germ cells in a mature teratoma and which all or a large part is composed of thyroid tissue. Malignant transformation and clinically evident metastatic disease are very rare. The rarity of malignant struma ovarii renders evaluation of treatment modality difficult. There is evidence that these tumors behave like their thyroid counter parts, and cytoreductive surgery followed by ablation with radioactive iodine has been advocated. We have experienced a case of malignant struma ovarii. In this report, we present clinical and pathological findings of a case of malignant struma ovarii of 51-year-old patient with a review of the concerned literatures.
