Pulmonary consolidation, rarefaction of adjacent ribs and pleural effusion, a triad frequently considered characteristic of actinomycosis, seemed in the present case to support this serologically entertained diagnosis. However, the subsequent course of disease disclosed the most uncommon association of actinomycosis an metastatic Ewing's sarcoma of the lung. The possibility of combined occurrence of an opportunistic infection by actinomyces and malignancy, calls for open biopsy in cases not responding to penicillin treatment or with an unexpected evolution of the clinical manifestations.
肺部实变、相邻肋骨稀疏及胸腔积液，这一常被视为放线菌病特征的三联征，在本病例中似乎支持血清学诊断的这一疾病。然而，疾病的后续病程显示出放线菌病与肺转移性尤因肉瘤这种极不常见的关联。放线菌机会性感染与恶性肿瘤合并发生的可能性，要求在对青霉素治疗无反应或临床表现出现意外演变的病例中进行开放性活检。
