Intrathyroid metastases are very rare and their mammary origin is exceptional. In this work, we report a case of intrathyroid metastasis in a patient who was treated for right breast cancer and who developed dysphonia forty months later. The diagnosis of thyroid metastasis was guided by PET/CT; the fine-needle aspiration and was confirmed by immunohistochemistry on the surgical sample. The patient was treated with chemotherapy, partial thyroidectomy and radiotherapy on the tumour bed. However, the appearance of diffuse visceral metastases caused the death. Intrathyroid metastases of breast cancer are very rare. A multidisciplinary approach is essential for the diagnosed, their management and prognosis would depend on the underlying breast cancer.
