“…Thyroid metastasis was found in a case reported by Wychulis et al in 1940 and in a case reported by Sklaroff et al in 1952. These older reports suggest that early detection was missed because of unavailability of accurate imaging techniques at that time [3, 5]. Therefore, the metastatic tumors might have been too advanced to allow complete resection in these three cases.…”

“…Almost all cases with metastasis of CRC to the thyroid have involvement of other organs, in particular the liver and/or lung. There are only three reports of CRC metastasis to the thyroid without involvement of another site [3–5]. Surgical resection is generally considered in patients with a solitary liver and/or lung metastasis from CRC [6].…”

Malignant metastases to the thyroid are rare and even rarer from colorectal cancer (CRC). Most cases of CRC metastasis to the thyroid involve metastases to other organs as well, particularly the liver and/or lung. There are only three reports of CRC metastasizing to the thyroid without involvement of another site. Patients with solitary thyroid metastasis from CRC have a poor prognosis after surgery, whereas resection is beneficial in their counterparts with a solitary liver or lung metastasis. This difference could be the result of delayed diagnosis of thyroid metastasis in patients with CRC, given that postoperative follow-up examination of the thyroid is not routinely performed. Here we describe a patient who was found to have a solitary metastasis of sigmoid cancer to the thyroid on postoperative imaging and has had prolonged disease-free survival after thyroidectomy. Our experience suggests that a low threshold of suspicion is crucial for timely diagnosis of thyroid metastasis from CRC and that resection can improve disease-free survival.
