Abstract
|
|
|
|
Struma ovarii (SO) is a rare ovarian teratoma, which is diagnosed when thyroid tissue accounts for more than 50% of the teratoma. The majority of SO are benign, but malignant tumors have been reported in a small percentage of cases. Five percent of SO cases have been proven to be malignant and, as in the thyroid gland, papillary carcinoma is the most common histotype arising in SO. Because this tumor is rare, there are no guidelines regarding the management of this cancer. Usually, total thyroidectomy followed by radioiodine treatment is the treatment of choice in metastatic malignant struma ovarii, but therapeutic decisions should be made individually based on clinical and pathological data. We recently experienced a case of a 45-year-old woman finally confirmed as malignant struma ovarii with cervical thyroid cancer. Therefore, we present this unique case with a review of the literature.
