His history included a low anterior resection of rectum in 9 months ago for a high-risk stage II rectal adenocarcinoma. He did not show clinical signs of hyperthyroidism other than thyroid enlargement. In thyroid nodule the FNA cytology, pathology reported anaplastic thyroid malignancy. Pathologists reported final diagnosis of colorectal metastasis of thyroid gland. Then due to metastatic pattern of disease, his pathology was evaluated for RAS molecular assay.
