Abstract

Struma ovarii is defined as a rare monodermal form of ovarian teratoma that occupies more than 50% of thyroid tissue. Only 2% of struma ovarii display malignant histology, most of which is revealed as papillary carcinoma type. Follicular carcinoma originating from malignant struma ovarii is rarely reported. We report a case of a pregnant woman diagnosed with peritoneal dissemination of follicular carcinoma arising from struma ovarii.
