甲状腺癌占甲状腺疾患約2.4—4.3％, 关于甲状限癌之分类,各专家意見不一,一股常按癌肿之恶性程度分为三类: 一、輕度恶性者:有乳头状囊暸瘤或腺瘤并具浸潤血管之趋势者。 二、中度恶性者:有乳头状和小饱状腺癌二类。 三、高度恶性者:包括直細胞型、小細胞型、Huerthle氏細胞癌三种未分化型癌及鱗状上皮細胞癌。 乳头状腺癌生长緩慢,轉移多局限于頸部患側之淋巴結;因此这些病人常可維持一定健康水平生存数年甚至十年以上,故归納入第二类。本文报告乳头状腺癌合并广泛之顱骨轉移病案一例。
Thyroid cancer accounts for about 2.4-4.3% of thyroid disorders. Regarding the classification of thyroid cancer, experts differ in their opinions. One group is often divided into three categories according to the degree of malignancy of the cancer: 1. Mild malignancy: There is a papillary sac. Tumors or adenomas with a tendency to infiltrate blood vessels. Second, moderately malignant: There are papillary and small satiety adenocarcinomas. Third, highly malignant: including direct cell type, small cell type, three undifferentiated carcinoma of Huerthle’s cell carcinoma and squamous cell carcinoma. Papillary adenocarcinoma grows slowly, and metastases are mostly confined to the lymph nodes on the affected side of the neck; therefore, these patients can often maintain a certain level of health to survive for several years or even more than ten years, so they are included in the second category. This article reports a case of papillary adenocarcinoma complicated with extensive skull metastases.
