The authors have encountered four cases of oil aspiration pneumonia complicated by carcinoma. Each had a clear-cut history of chronic intake of an oily substance, radiographic changes, and histologically documented oil aspiration pneumonia. Lung cancer later appeared in the involved area. A small number of similar cases also have been reported. The implication is that oil aspiration pneumonitis may induce bronchogenic carcinoma, particularly either the alveolar cell or the squamous cell variety. The radiographic diagnosis of the malignant transformation is difficult, and consequently the prognosis is poor.
作者遇到了4例油吸入性肺炎并发癌症的病例。每例都有明确的长期摄入油性物质的病史、影像学改变以及组织学证实的油吸入性肺炎。肺癌随后出现在受累区域。也有少数类似病例的报道。这意味着油吸入性肺炎可能诱发支气管源性癌，尤其是肺泡细胞癌或鳞状细胞癌。恶性转化的影像学诊断困难，因此预后较差。
