Τhe case is described of a patient with malignant transformation of thyroid tissue in a mature ovarian teratoma. Rarely ovarian teratomata contain thyroid tissue in which malignant transformation is observed. A 38-year old female patient presented with a clinically silent ovarian neoplasm discovered incidentally during investigation for metrorrhagia. The patient was treated by ovariectomy. The ovarian mass was found on histology to be a teratoma. Within the teratoma a papillary thyroid carcinoma was observed. Near-total thyroidectomy was subsequently performed and the resected thyroid was found to be normal on histology. Subsequently whole body scanning with 131I and ablation of the thyroid remnant by the administration of 80 mCi 131I was performed.

Key words: Malignant, Ovarian teratoma, Thyroid carcinoma.
