title: Thyroid gland metastasis of rectal cancer.
abstract: A 72-year-old woman with a history of rectal cancer was admitted to our hospital to undergo thyroidectomy and left adrenalectomy. She had undergone low anterior resection and regional lymph node dissection for rectal cancer 52 months pre-admission (T3 N1 M0, stage IIIb according to International Union Against Cancer tumor-node-metastasis), and she had also undergone metastasectomy for lung metastases and right adrenal gland metastasis after the rectal surgery. Follow-up computed tomography scans detected nodules in the bilateral lobes of the thyroid gland and in the left adrenal gland. Subtotal thyroidectomy and left adrenalectomy were performed, and pathological examination revealed metastases of rectal cancer to the thyroid gland and left adrenal gland.
