Insular carcinoma of thyroid is a rare tumor, which accounts for 4 to 6% of thyroid malignancies. Clinically and morphologically it is considered to be in an intermediate position between well-differentiated carcinoma of the thyroid (papillary or follicular) and undifferentiated or anaplastic carcinoma of the thyroid. Capsular and blood vessel invasion is seen frequently, and metastases to regional lymph nodes, lungs and bones are common. The initial presentation of distant metastasis in patients with thyroid cancer is rare. Thus metastatic thyroid carcinoma rarely involves the orbit. We report a rare case of choroidal metastasis from insular thyroid carcinoma.
甲状腺岛状癌是一种罕见的肿瘤，约占甲状腺恶性肿瘤的 4%至 6%。从临床和形态学上看，它被认为是分化良好的甲状腺癌（乳头状或滤泡状）与未分化或间变性甲状腺癌之间的中间状态。常可见包膜和血管侵犯，局部淋巴结、肺和骨转移也很常见。甲状腺癌患者的远处转移的初始表现较为罕见。因此，转移性甲状腺癌很少累及眼眶。我们报告了 1 例罕见的甲状腺岛状癌引起脉络膜转移的病例。
