<p>Metastases to the thyroid cartilage are rare due to the absence of vessels within cartilaginous tissue. Herein, we report a rare case of thyroid cartilage metastasis in a patient treated for rectal cancer.</p><p>An 80-year-old male patient who had undergone low anterior resection for rectal cancer presented with multiple metastases. 9 months later, and underwent partial liver resection and pelvic tumor removal. One year after the first operation, he presented with throat pain and was found to have airway obstruction. Computed tomography of the neck showed a tumor in the thyroid cartilage. We performed tracheostomy and histopathological examination of the neck tumor revealed metastasis from rectal cancer. The thyroid cartilage metastasis gradually grew in size, the patient complained of pain, and we performed radiation therapy. The tumor shrank, however, other metastases increased in size, and the patient received palliative treatment.</p><p>Our review of the literature published between 1983 and 2021 revealed that the most frequently encountered metastatic cancer to the head and neck region from the thoracoabdominal viscera is metastasis of renal cancer to the paranasal sinuses, the most frequent primary lesion is in the kidney and the most frequent metastatic lesion is in the thyroid.</p>
