Struma ovarii
Struma Ovarii
Struma ovarii (pronounced: stroo-ma ov-ahr-ee-eye) is a rare type of ovarian teratoma that contains predominantly thyroid tissue. The term "struma" is derived from the Latin word for "swelling", which in this context refers to the swelling of the ovary due to the presence of thyroid tissue.
Definition
Struma ovarii is a monodermal variant of ovarian teratoma, characterized by the presence of thyroid tissue covering more than 50% of the overall histology. It accounts for less than 1% of all ovarian tumors.
Symptoms
The symptoms of struma ovarii are often non-specific and can mimic those of other ovarian tumors. These may include abdominal pain, bloating, and irregular menstrual periods. In some cases, the tumor can lead to hyperthyroidism, a condition characterized by overactivity of the thyroid gland.
Diagnosis
Diagnosis of struma ovarii is typically made through a combination of physical examination, imaging studies such as ultrasound or computed tomography (CT) scan, and histological examination of the tumor tissue. Blood tests may also be performed to assess thyroid function.
Treatment
Treatment for struma ovarii typically involves surgical removal of the tumor. In some cases, additional treatment such as radioactive iodine therapy may be necessary, particularly if the tumor is malignant or if there is evidence of hyperthyroidism.
Prognosis
The prognosis for individuals with struma ovarii is generally good, particularly if the tumor is benign and is completely removed through surgery. However, regular follow-up is necessary to monitor for potential recurrence of the tumor.
