目的 总结近十年期间该院的神经鞘瘤患者９０ 例细胞学诊断的体会及经验。 方法 应用细针穿刺涂片，ＨＥ染色，光镜观察，并与组织病理学诊断相对照。 结果 手术前穿刺细胞学诊断或提示为神经鞘瘤者５５例占６１－１２％ ；诊断为软组织良性肿瘤或良性病变者２０ 例占２２－２２％ ；漏诊１１ 例占１２－２２％ ；误诊４ 例占４－４４％ 。 结论 来自颅神经的神经鞘瘤由于在穿刺时其放射性酸麻感不及来自臂丛神经的神经鞘瘤明显，故给细胞学诊断带来了一定的难度。造成漏诊的主要原因是未穿刺到具有诊断价值的肿瘤细胞。神经鞘瘤还需与颈淋巴结的转移性低分化鳞癌相鉴别
Objective To summarize the experience and experience of 90 cases of schwannoma in patients with schwannomas in the past ten years. Methods Fine needle aspiration smear, HE staining and light microscopy were used to observe the histopathological diagnosis. Results The results of preoperative puncture cytology diagnosis or suggestive of schwannoma 55 cases accounted for 61-12%; diagnosed as benign soft tissue tumors or benign lesions in 20 cases accounted for 22-22%; 11 cases missed 12-22%; misdiagnosed 4 Cases accounted for 4-44%. Conclusion Schwannoma from the cranial nerves due to puncture when the radioactive tingling less than from the brachial nerve Schwannoma obvious, so to the cytology to bring a certain degree of difficulty. The main reason for missed diagnosis is not puncturing tumor cells of diagnostic value. Schwannoma need to differentiate from metastatic poorly differentiated squamous cell carcinoma of the neck
