Abstract

Follicular thyroid carcinoma (FTC) is the second most common thyroid cancer, following papillary carcinoma. Metastasis to the orbital rim from FTC is very rare. We recently experienced a case of FTC with metastasis to the orbital rim in a 74-year-old woman, who initially presented with a huge thyroid mass and an asymptomatic solitary orbital rim lesion. The solitary orbital rim lesion was suspected to be a separate disease entity such as lymphoma from the preoperative imaging, but bone metastasis from FTC was finally confirmed after orbital rim resection and total thyroidectomy. During follow-up, the patient presented multiple bone metastasis, so the solitary orbital rim lesion was considered a clinical sign of systemic metastasis from FTC. Therefore, we present this unique case with a review of the literature.
