[Multi-modality therapy concept in metastatic follicular thyroid carcinoma with hyperthyroidism]

Abstract

The coincidence of hyperthyroidism and thyroid carcinoma seldom occurs. Only few reports on functionally metastases of thyroid carcinoma have been published. We report a 59-year-old man who underwent subtotal thyroidectomy for toxic nodular goiter. Histological examination revealed a follicular thyroid carcinoma. After thyroidectomy and cervical lymphadenectomy the patient developed a strong hyperthyreosis. Scintigraphy showed strong radioiodine uptake in the sacrum. De-bulking resection of the metastasis followed by high-dose radioiodine treatment was performed. After radioiodine therapy the patient became euthyroid. Treatment of hyperthyreosis in metastatic thyroid cancer requires a multimodal therapeutic concept.
