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.
