Eosinophilic pneumonia is characterized by pulmonary infiltrates visible on radiography, eosinophilic infiltration into the lung parenchyma, and frequent peripheral eosinophilia. The etiology may be idiopathic or secondary to identifiable causes, including drugs, parasites, toxins, infections, or systemic diseases such as hypereosinophilic syndrome. A 60-year-old man was seen in pulmonary clinic with 4 weeks of cough and wheeze. He was found to have pulmonary infiltrates, a peripheral eosinophilia, and bronchoalveolar lavage demonstrated numerous eosinophils. Careful review of history revealed that the symptoms had started after a recreational exposure to marijuana from a different source than usual. Eosinophilic pneumonia from marijuana has been described once in conjunction with tobacco smoke in the pediatric literature, but to our knowledge this is the first report in the adult literature.
嗜酸性粒细胞性肺炎的特征是胸部X光片可见肺部浸润、肺实质嗜酸性粒细胞浸润以及外周血嗜酸性粒细胞增多。病因可能是特发性的，也可能继发于可识别的原因，包括药物、寄生虫、毒素、感染或系统性疾病，如高嗜酸性粒细胞综合征。一名60岁男性因咳嗽和喘息4周就诊于肺部门诊。他被发现有肺部浸润、外周血嗜酸性粒细胞增多，支气管肺泡灌洗显示有大量嗜酸性粒细胞。仔细回顾病史发现，症状始于一次与往常不同来源的娱乐性接触大麻之后。小儿文献中曾有过一次将大麻所致嗜酸性粒细胞性肺炎与烟草烟雾联系起来的描述，但据我们所知，这是成人文献中的首例报告。
