Abstract
A 22-year-old woman with thyroid carcinoma and coincident Graves' disease is reported. She was preoperatively treated with antithyroid medication for hyperthyroidism and subtotal thyroidectomy was performed 7 months later. Eighteen months after the operation, she remained euthyroid and no recurrence of malignancy. Pathological examination revealed that the tumor was papillary carcinoma.
We reviewed the reported frequency of coexisting thyroid carcinoma and Graves'disease.
