甲状腺肿瘤的WHO组织学分类第一版,由病理工作者在1964和1972年间的甲状腺国际会议上提出,于1974年出版,为临床、病理及流行病学研究奠定了基础。但此后,在甲状腺病理研究的某些领域内已有许多重要变化。因此,1986年在瑞士苏黎世召开的甲状腺肿瘤组织学分类会议上,WHO协作中心对原分类进行了修改(见表)。与原分类相比较,修改后的分类删除了未分化癌的亚型(包括小细胞癌);鳞癌不再作为一种主要肿瘤类型;修正

Therefore, at the thyroid cancer histological classification conference held in Zurich, Switzerland, in 1986, the WHO Collaborating Center revised the original classification (see table). Compared with the original classification, the revised classification deleted the subtypes of undifferentiated cancer (including small cell carcinoma); squamous cell carcinoma is no longer as a major tumor type;
