Cutaneous metastases from thyroid carcinoma are rare. This report describes four cases of thyroid carcinoma metastatic to the skin. Two cases were medullary carcinoma and two were papillary thyroid carcinoma. In two cases, skin metastases were the presenting feature of the underlying thyroid carcinoma. Examination of the skin lesions by conventional light microscopy suggested the possibility of metastatic carcinoma and immunohistochemical tests confirmed the diagnosis. Subsequent investigations identified primary thyroid lesions. In two cases, the skin metastasis was the first evidence of the recurrence of known thyroid carcinoma. These cases identify a novel presentation of thyroid carcinoma.
甲状腺癌的皮肤转移罕见。本报告描述了4例甲状腺癌转移至皮肤的病例。2例为髓样癌,2例为乳头状甲状腺癌。在2例中,皮肤转移是潜在甲状腺癌的首发表现。通过传统光学显微镜检查皮肤病变提示有转移癌的可能,免疫组化检测确诊了诊断。随后的检查发现了原发性甲状腺病变。在2例中,皮肤转移是已知甲状腺癌复发的首个证据。这些病例确定了甲状腺癌的一种新表现形式。
