Abstract

Metastasis to the thyroid gland is a rare event. To date, only 11 cases of metastasis from neuroendocrine tumors (NETs) originating in the lung have been reported. We present a case of a patient in his 40s harboring two nodules in the thyroid gland that were diagnosed as well-differentiated NET (G1). Eighteen years before the patient underwent a lung lobectomy of the right upper lobe for a bronchial typical carcinoid with metastasis in one lymph node. Normal blood levels of calcitonin virtually ruled out the diagnosis of medullary thyroid carcinoma (MTC) and supported the diagnosis of a possible thyroid metastasis of the previous bronchial NET. Mutational analysis performed on both primary and metastasis tumor tissue did not show any mutation in the 409 genes analyzed.
