Malignant Struma Ovarii With Graves’ Disease and Papillary Thyroid Carcinoma: A Case Report

Abstract

Malignant struma ovarii is a rare ovarian teratoma consisting predominantly of thyroid tissue. Herein, we report the case of a young woman with no history of coitus and with Graves’ disease who was ultimately diagnosed with coexistent malignant struma ovarii and papillary thyroid carcinoma. The patient underwent surgery, including unilateral salpingo-oophorectomy and single-port robotic bilateral total thyroidectomy. To ensure future fertility, oocyte cryopreservation was performed preoperatively. She also underwent postoperative radioactive iodine therapy and was stable postoperatively.
