- Struma ovarii is a rare type of ovarian tumor defined by the presence of thyroid tissue comprising more than fifty percent of the tumor mass.
- SUMMARY A case of benign struma ovarii, which is a rare ovarian tumor, is presented here and associated litera ture is reviewed.
- Objective: Struma ovarii is a rarely seen ovarian tumour that usually diagnosed in postoperative period by pathological examina-tion.
- Surgical removal is the treatment for struma ovarii, even in a patient with coexisting Graves’ disease or toxic nodular goiter, due to the risk of carcinoma.
- Struma ovarii is a mature teratoma and accounts for approximately 3% of all ovarian teratomas.
- Struma ovarii is a rare ovarian tumor that is composed entirely or predominantly of thyroid tissue.
- Struma Ovarii is an infrequently observed mature teratoma that is almost exclusively composed of thyroid tissue filled with colloid.
- Figure 1: Photomicrograph of struma ovarii- clearly showing thyroidal acini lined with low cuboidal epithelium and filled with colloid along with ovarian stromal tissue.
- Struma ovarii or monodermal teratoma is a specialized ovarian neoplasm which mainly constitutes mature thyroid tissue.
- Method: A retrospective institutional analysis of 2 patients with malignant and 14 patients with benign struma ovarii, treated during a period of 20 years.
