Abstract

About 15-20% of ovarian tumors are teratomas. Struma ovarii is a highly specialized form of ovarian teratoma, in which thyroid tissue is the predominant element. It is rare, comprising about 2% of all teratomas, and malignant transformation occurs in less than 5% of struma ovarii. Among the malignant struma ovarii, papillary type is the most common histologic type. However, because of the rarity of malignant struma ovarii, there is considerable confusion concerning management. Recently, the authors experienced a case of papillary thyroid carcinoma arising in struma ovarii found in a postmenopausal woman who presented with adnexal mass and underwent laparoscopic unilateral salpingoophorectomy. Therefore, we report this rare case with a brief review of the literature.
