The thyroid gland is exceptionally a metastatic site. Thyroid metastasis from a testicular seminoma is even more exceptional. We report the case of a patient with an atypical 8-cm thyroid nodule showing the histology and the immunoprofile of a pure seminoma. No testicular or extra-testicular tumor was discovered. To our knowledge, this situation has never been described. After surgery, the patient underwent chemotherapy and remains disease-free four years later.
