[Thyroid metastasis due to right colonic carcinoma].
Clinical evident metastases to the thyroid gland are rarely found antemortem. A case of a 62 year-old man with a history of right colonic carcinoma, who presented a mass in the right lobe of his thyroid gland one year after the removal of a metachronous metastasis in his right lung, is presented. The tumour of the thyroid was found to be metastatic adenocarcinoma from his previous colonic cancer. The clinical finding of metastases to the thyroid gland is rare, particularly from a colorectal primary neoplasm. However, the possibility of a tumour of the thyroid gland representing a secondary malignancy is to be considered in any patient with a prior history of cancer.
