A 65-year-old woman underwent laparoscopic low anterior resection for rectal cancer with distant metastasis to the right lobe of her liver and mediastinal and right subclavian lymph nodes. Since the postoperative chemotherapy resulted in the disappearance of the lymph node metastasis and diminished hepatic metastasis lesion, the enlarged anterior segment of the liver was performed. She was administered chemotherapy for 1 year after the second surgery. Thoracoabdominal computed tomography performed 18 months after the end of the treatment revealed swelling of the left lobe of the thyroid. Ultrasonography showed a 23mm lobulated hypoechoic tumor in the left lobe of the thyroid gland. We suspected thyroid metastasis by aspiration biopsy cytology. Left thyroid lobectomy was performed for definitive diagnosis and local control. Histological examination revealed thyroid metastasis of the rectal cancer. We experienced a rare case of thyroid metastasis from rectal cancer.
一名65岁女性因直肠癌伴肝右叶、纵隔及右锁骨下淋巴结远处转移接受了腹腔镜低位前切除术。由于术后化疗使淋巴结转移消失且肝转移病灶缩小，遂对增大的肝前段进行了手术。第二次手术后她接受了1年的化疗。治疗结束18个月后进行的胸腹部计算机断层扫描显示甲状腺左叶肿大。超声检查显示甲状腺左叶有一个23mm的分叶状低回声肿瘤。通过细针穿刺活检细胞学检查，我们怀疑为甲状腺转移。为明确诊断和进行局部控制，实施了左甲状腺叶切除术。组织学检查显示为直肠癌甲状腺转移。我们遇到了一例罕见的直肠癌甲状腺转移病例。
