Bilateral choroidal metastasis of follicular thyroid carcinoma 7 years after total thyroidectomy: a case report

ABSTRACT

ABSTRACT Follicular thyroid cancers account for 15%-20% of all thyroid tumors. Choroidal metastases secondary to follicular thyroid cancer rarely occur. Herein, we report the case of an 85-year-old woman who presented choroidal metastasis from a follicular thyroid carcinoma in the right eye 7 years after total thyroidectomy and underwent enucleation. To confirm the diagnosis and primary tumor site, histopathological, and immunohistochemical examinations were performed. One year later, she presented metastasis in the contralateral eye. Few similar cases have been described in the literature.
