Abstract

Thyroid metastasis from colon cancer is very rare and the prognosis is very poor. We present a rare case of thyroid metastasis from descending colon cancer. A 50-year-old man was visited because of palpable neck mass. He was diagnosed stage III colon cancer 51 months before symptom presentation. He has also underwent palliative chemotherapy and radiotherapy for distant metastasis of colon cancer. Imaging study showed a left side deviation of trachea due to 3.3 cm sized right thyroid gland mass which was suspicious of metastasis. The patient underwent right thyroid lobectomy. Histopathologic examination and immunohistochemistry revealed adenocarcinoma which was consistent with a diagnosis of metastases from primary colon cancer to the thyroid gland. Surgeon should consider the operation that distant metastasis to the thyroid gland is possible among the patients who present compression symptom on the neck.
