Supplementary Material for: Malignant struma ovarii (papillary carcinoma) with hyperthyroidism: A case report and literature review

Malignant struma ovarii (MSO) is an extremely rare monodermal ovarian teratoma. Preoperative diagnosis and intraoperative freezing diagnosis are exceedingly difficult due to the rarity of the disease and its clinically non-characteristic manifestations with less than 200 reports in the current literatures. In this paper, a case of malignant struma ovarii (papillary carcinoma) with hyperthyroidism was discussed in terms of its epidemiology, clinicopathology, molecular features, treatment and prognosis.
