Misdiagnosis of idiopathic inflammatory myopathy:analysis of 16 cases

目的总结特发性炎症性肌病的临床表现,分析误诊原因,从而提高认识。方法回顾性分析1993年1月至2006年12月在我院确诊的特发性炎症性肌病的误诊情况。结果特发性炎症性肌病初诊时误诊为其他疾病共16例,误诊率高达22.22%。误诊疾病包括敏感性皮炎、药物疹、荨麻疹等皮肤疾病共6例(6/16),肺部病变5例(5/16),肝功能异常2例(2/16),风湿热2例(2/16),心律失常1例(1/16)。误诊病例的最后确诊时间从半月至6月不等。结论特发性炎症性肌病临床表现复杂,容易被误诊,尤其早期肌病不明显患者,临床上应引起重视。
