目的探讨甲状腺乳头状癌的细胞学特征及针吸细胞学在其诊断中的作用。方法对70例经病理组织学确诊的甲状腺乳头状癌术前进行细针穿刺的细胞学病例回顾性分析。结果甲状腺乳头状癌的细胞学特征:乳头状结构,核内包涵体及核沟,毛玻璃样核,并可见砂粒体,多核巨细胞。结论细针穿刺诊断甲状腺乳头状癌的主要依据是:乳头状结构,核内包涵体及核沟,次要依据是毛玻璃核,砂粒体,多核巨细胞。
Objective To investigate the cytological features of papillary thyroid carcinoma and the role of needle aspiration cytology in its diagnosis. Methods Retrospective analysis of 70 cases of papillary thyroid carcinoma diagnosed histopathologically by fine needle aspiration before surgery. Results Cytological features of papillary thyroid carcinoma: Papillary structures, inclusions in the nucleus, ditch nucleus, ground vitreous nuclei, and the presence of sand bodies and multinucleated giant cells. Conclusion The main basis of fine needle aspiration diagnosis of papillary thyroid carcinoma is papillary structure, inclusions and nuclear ditch in the nucleus. The secondary basis is the ground glass nucleus, the sand body and the multinucleated giant cells.
