Abstract
Introduction: Papillary carcinoma arising from thyroid tissue in mature cysticteratoma (MCT) of the ovary is extremely rare, and it is not easy to diagnose preoperatively. No clinical, no radiological, no biological signs are specific to malignant transformation. Case presentation: A 51-year-old woman had a left ovarian tumor measuring approximately 18 cm diameter with malignant transformation of a mature cysticteratoma, who was diagnosed postoperatively with follicular variant of papillary thyroid carcinoma. A laparoscopic hysterectomy and left salpingo-oophorectomy were performed. During surgery, there were no signs of invasion or metastasis. Conclusion: Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radio ablation if residual disease is identified.

Summary
Mature cystic teratoma commonly referred to as a dermoid cyst of the ovary It is the most common type of ovarian teratoma and germ cell neoplasm comprising 10% - 20% of ovarian tumors in the female reproductive period [1]. Unilateral, it is, by definition, composed of well-differentiated derivates which originate from all three layers. We report a rare case of follicular variant papillary thyroid cancer arising from a mature cystic teratoma of the ovary, which was unexpectedly discovered during histopathologic examination
