细针吸取细胞学对甲状腺肿瘤的诊断与鉴别诊断

Diagnosis and Differential Diagnosis of Thyroid Neoplasms by Fine Needle Aspiration Cytology

本文通过甲状腺肿瘤细针吸取细胞学涂片观察和结合文献，对甲状腺癌细胞中出现的某些特征：核内包涵体、核沟细胞、毛玻璃样核、乳头状结核作了详细的描述。研究显示：核内包涵体在乳头状癌中多见，可作为诊断乳头状癌的重要指标；核沟细胞在滤泡癌和乳头状癌中均可见到，但数量少，对诊断癌有一定价值；甲状腺癌细胞中罕见上述癌之特征。研究还发现，甲状腺癌细胞核普遍增大至１０～１２μｍ以上，并具备其它恶性指征。文章对甲状腺良恶性肿瘤细胞诊断和鉴别亦作了概括。

The cellular characteristics such as containing psammoma bodies,nuclei showing longitudinal grooving,ground-glass nuclei and papillary fronds of smear were illustrated in detailby using fine needle aspiration cytology (FNAC)in thyroid neoplasms. The results showedthat nuclei containing pasmmoma bodies in papillary carcinoma were more than in others,which plays animportment role in the diagnosis of thyroid papillary carcinoma. The cells ofnuclei showing longitudinal grooving were observed both in follicular carcinoma and papillarycarcinoma,it was useful in the diagnosis of thyroid carcinoma though its number was fewer,In thyroid adenomas,the characterization above was seldom seen. We also found that the diameters of nuclei in thyroid carcinoma were over 10-20 μm,and showed other character ofmalignant cells. In this study,we summarized the diagnosis and differentil diagnosis of thyroid neoplasms in cytoloy asso.
