DEAR DR. GOTT: What can you tell me about struma ovarii? Is it serious, etc?
DEAR READER: Struma ovarii is a rare type of ovarian tumor, accounting for only 1% of all ovarian tumors. It is characterized by the presence of thyroid tissue as a major cellular component of the tumor. Because this is a cancer of the female reproductive tract, only women are affected, with those between the ages of 40 and 60 most commonly affected.
The condition typically presents with a pelvic mass and signs and symptoms similar to those of other types of ovarian and female reproductive tract tumors/lesions. Rarely, but in a few instances, some sufferers may develop hyperthyroidism (which disappears following treatment) and ascites (a buildup of fluid in the abdomen). Some women may also present with an elevated CA-125 level.
Surgical removal of the lesion is definitive first step in every case; benign (noncancerous), malignant (cancerous), and recurrent tumors. For those with recurrent or malignant tumors, radio iodine therapy may be beneficial, due to the presence of the thyroid tissue. For some, complete hysterectomy to include the ovaries and thyroidectomy may be appropriate. Recurrence is uncommon.
Those individuals diagnosed with this type of tumor should be under the care of a specialist familiar with treating it, such as a gynecologist or gynecological oncologist.
