目的：探讨涎腺肌上皮瘤的细胞学表现及误诊。研究设计：对7例涎腺肌上皮瘤的细胞学特征进行分析，其中浆细胞型3例，梭形细胞型2例，混合型2例。诊断为浆细胞瘤或细胞性多形性腺瘤3例，良性梭形细胞瘤2例，细胞性多形性腺瘤2例。未见有丝分裂和明显的多形性。结论：细针吸取涂片诊断肌上皮瘤较为困难。核纹(斑马线)5例。这一发现在之前发表的论文中没有报道。
OBJECTIVE: To evaluate the cytologic findings and pitfalls in the diagnosis of myoepithelioma of the salivary glands.STUDY DESIGN: Smears from 7 cases of myoepithelioma of the salivary glands, 3 plasmacytoid, 2 spindle and 2 mixed types, all histologically confirmed, were evaluated with special attention to cytologic features that may be helpful for the diagnosis.RESULTS: A correct cytologic diagnosis was not made in any of the cases. Three were diagnosed as plasmacytomas or cellular pleomorphic adenomas, 2 as benign spindle cell tumors and 2 as cellular pleomorphic adenomas. Mitoses and marked pleomorphism were absent. Nuclear striations were noted frequently.CONCLUSION: Diagnosis of myoepithelioma was difficult on fine needle aspiration smears. Nuclear striations (zebra lines) were noted in 5 cases. This finding is not reported in previously published papers.
