Struma ovarii - A report of seven cases

Struma ovarii is a rare ovarian teratoid tumor. Thyroid elements can be noted in almost 20% of the cases of dermoid cyst, however the term ‘struma’ is used when the thyorid tissue constitutes more than 50% of the tumor . The malignant struma ovarii is even more rare, and makes about 5% of all cases of struma ovarii . Majority of the references are in the form of case reports in the literature. We present a report of seven cases of struma ovarii, which include six cases of benign struma ovarii and one case of malignant struma ovarii.
