细针穿刺细胞学及细胞块技术在颈部肿大淋巴结诊断的意义

目的探讨细针穿刺细胞学联合细胞块技术对于明确诊断颈部肿大淋巴结的意义。方法选择颈部肿大淋巴结病例109例行细针穿刺涂片并制备细胞块切片，必要时行免疫细胞化学染色检测，比较单纯常规穿刺涂片与涂片联合细胞块切片检查结果，分析相应技术诊断的准确性。结果109例中，单纯常规细针穿刺涂片与最终诊断的符合率仅为54．1％，联合细胞块切片符合率为78．9％，免疫细胞化学染色检查后符合率则达到95．4％。结论常规细针穿刺涂片联合细胞块切片及免疫细胞化学染色对于颈部肿大淋巴结诊断有较高的应用价值，但对于少数差分化肿瘤及恶性淋巴瘤的诊断存在一定局限性。

Diagnostic Significance of the Fine Needle Aspiration Cytologyand Cell Block Technology in Cervical Lymphadenopathy

Objective To explore the diagnostic significance of combined use of the fine needle aspiration cytology （FNAC） and cell block technique （FNACB） in the cervical lymphadenopathy. Methods 109 cases of cervical lymphadenopathy were examined by combined FNAC and FNACB as well as immunocytochemistry （ICC） when necessary, and compared with FNAC only to analyze the diagnostic accuracy. Results The diagnostic accuracy of FNAC, FNAC 4- FNACB, and FNAC 4- FNACB 4- ICC was 51.4%, 78. 9% and 95. 4%o, respectively. Conclusion FNAC combined with FNACB and ICC is of higher diagnostic value but has some limitations in accurate diagnosis of poorly differentiated carcinomas and malignant lymphoma.
