目的 探讨非何杰金氏淋巴瘤的针吸细胞学形态特征及诊断中的意义。方法 对 17例淋巴瘤及 2例淋巴结反应性增生用细针吸取细胞学诊断 ,并将针吸标本用 2 0 %琼脂作依托再按常规扫描电镜 ,透射电镜技术分别制样观察 ,部分手术切除标本用石腊切片HE染色 ,常规透射电镜制样供观察。结果 淋巴结反应性增生 ,细胞形态多样呈弥漫分布 ,有T、B细胞来源的 ,可见大、小淋巴细胞及浆细胞等。结论 瘤细胞形态具有明显异型性以及单一性 ,T细胞淋巴瘤和B细胞淋巴瘤瘤细胞各有不同的超微病理学特征 ,具有诊断价值
Objective To investigate the features of needle aspiration cytology of non-Hodgkin’s lymphoma and its significance in diagnosis. Methods Cytological diagnosis was performed on 17 cases of lymphomas and 2 cases of reactive hyperplasia of lymph nodes with needles. The needle specimens were supported on 20% agar and then observed by conventional scanning electron microscope and transmission electron microscope. Some surgical resections were performed. Paraffin sections were stained with HE and routine transmission electron microscopy was used for observation. Results Lymph node reactive hyperplasia, diffusely distributed cell morphology, with T, B cell origin, visible large and small lymphocytes and plasma cells. Conclusion The morphology of neoplastic cells has obvious heterotypic and single nature. T-cell lymphoma and B-cell lymphoma have different ultrastructural features and have diagnostic value.
