This article reports the diagnosis and treatment of a rectal neuroendocrine neoplasm metastasis to the thyroid. No similar cases have been reported before. This case suggests that when evaluating thyroid tumors, clinicians should not only carefully identify the clinical features of the tumor but also pay special attention to the patient’s history of tumors, especially neuroendocrine neoplasms. Fordefinite secondary thyroid malignancies, neck surgery is feasible if the thyroid is the only site of metastasis; otherwise, the subsequent diagnosis and treatment plan should be determined after a comprehensive evaluation of the primary tumor and patient’s general condition.  \nKEYWORDS  \nneuroendocrine tumor, neoplasm metastasis, thyroid gland, rectal cancer, FNA  \n1 Introduction  \nThyroid metastases (TMs) refer to a class of diseases that metastasize from nonthyroid malignancies to the thyroid. A retrospective study by Ghossein CA (1) found that the incidence of TM was 0.36% among all patients with thyroid malignancies who visited the center from 2003 to 2019. According to Tang Q (2), who reviewed the literature from 1979 to 2021, the most common origins of metastasis in these patients were renal cell carcinoma (48.1%), colorectal cancer (10.4%), lung cancer (8.3%), breast cancer (7.8%) and sarcoma (4.0%) . The majority of colorectal cancer metastases to the thyroid originate from colorectal adenocarcinoma (3–5), and no cases of metastasis from rectal neuroendocrine neoplasms (NENs) to the thyroid gland have been reported.
