4例多形性脂肪瘤的针吸细胞学诊断体会

Diagnosis experience of fine needle aspiration cytology of 4 cases with pleomorphic lipoma

目的探讨针吸细胞学对多形性脂肪瘤的诊断要点与价值。方法回顾4例多形性脂肪瘤的FNAC资料及相关临床表现,并复习相关文献,分析总结FNAC诊断要点。结果多形性脂肪瘤的细胞形态学具有欺骗性,无诊断经验者易误诊为软组织恶性肿瘤。但掌握其细胞学特点后可报告:细胞形态符合多形性脂肪瘤表现。结论结合临床表现,根据细胞学特征,尤其是花环状多核巨细胞的出现,FNAC可对多形性脂肪瘤作出明确的符合性诊断。

Objective To explore the diagnostic criteria and clinical value of fine needle aspiration cytology for pleo-morphic lipoma. Methods The data of the FNAC and related clinical manifestations of 4 cases of pleomorphic lipoma were reviewed and literatures on FNAC were observed, analyzed the diagnostic criteria of FNAC in cytological features. Results Cytological features of pleomorphic lipoma were deceptive, and were easy to be misdiagnosed as a mali-gnant soft tissue tumor by no diagnostic experience. Cytological features were conformed with pleomorphic lipoma＇s manifes-tations that could be reported through mastering the cytological features. Conclusion According to the cytological fea-tures, combined with clinical manifestations, especially the appearance of multinucleated giant cells, FNAC can make a definite diagnosis of pleomorphic lipoma.
