Abstract:
Metastasis to the thyroid is uncommon. Mostly, they are tumors that originate in the lung or head or neck. Metastases from breast or kidney carcinomas and metastatic melanoma have also been reported. Autotransplantation of benign thyroid tissue is a surgical procedure designed to achieve normal thyroid hormonal status following surgery. Metastasis into autotransplanted thyroid tissue has not been reported earlier. We report a case of squamous cell carcinoma (SCC) metastatic to autotrasplanted thyroid diagnosed on fine-needle aspiration. Further workup revealed a primary oral cavity SCC.
