目的 :研究淋巴瘤细针吸取细胞学 (FNAC)的形态特征及其在诊断中的价值。　方法 :对 2 7例淋巴瘤进行细针吸取细胞学及组织学检查 ,并运用免疫组化ABC法检测 ,3例作透射电镜观察。　结果 :2 7例淋巴瘤中 ,细胞学确定诊断淋巴瘤 12例 ,霍奇金淋巴瘤 3例 ,分类诊断准确率为 5 5 .6 % (15 / 2 7) ;细胞学高度怀疑淋巴瘤 8例 ,均经组织学证实为淋巴瘤 ,细胞学分类诊断符合率为 85 .2 % (2 3/ 2 7) ;细胞学诊断转移性癌 3例 ,2例经组织病理检查诊断为T细胞性淋巴瘤 ,1例为B细胞性淋巴瘤。细胞学诊断反应性增生 1例 ,组织学证实为B细胞性淋巴瘤。全部病例诊断阳性率 96 .3% (2 6 / 2 7)。　结论 :针吸细胞学检查对初筛淋巴结疾患的良恶性及肿瘤类型有重要意义。组织学检查能确定肿瘤的性质、组织起源与分类。免疫组化技术对淋巴瘤的分型具有重要参考价值 Objective: To study morphological characteristics of lymph node fine needle aspiration cytology (FNAC) and its value in the diagnosis. Methods: Twenty-seven lymphoma samples were obtained by fine needle aspiration cytology and histological examination. Immunohistochemical ABC method was used to detect the lymph nodes. Three cases were examined by transmission electron microscopy. Results: Twenty-seven lymphoma samples were confirmed by cytology in 12 cases of diagnosed lymphoma and 3 cases of Hodgkin’s lymphoma. The diagnostic accuracy rate was 55.6% (15/27). Cytology highly suspected lymphoma 8 Cases were confirmed by histology as lymphoma, the diagnostic accuracy of cytological classification was 85.2% (23/27), cytology diagnosis of metastatic carcinoma in 3 cases, 2 cases diagnosed by Tissue and pathology as T cell Lymphoma, 1 case of B-cell lymphoma. Cytological diagnosis of reactive hyperplasia in 1 case, histologically confirmed as B cell lymphoma. The positive rate of all the cases was 96.3% (26/27). Conclusions: Needle aspiration cytology is of great importance for the screening of benign and malignant tumors and the type of tumor. Histological examination can determine the nature of the tumor, the origin and classification of the tissue. Immunohistochemical techniques for the classification of lymphoma has important reference value
