Lung toxicities resulting from the chemotherapeutic agent bleomycin encompass a variety of pathological changes, including bronchiolitis obliterans organizing pneumonia, interstitial pneumonitis and progressive interstitial fibrosis. We report a rare case of eosinophilic pneumonia associated with bleomycin.
A 44-year-old Hispanic man with a primary mediastinal seminoma complicated by superior vena cava syndrome underwent treatment with four cycles of bleomycin, etoposide and cisplatin. He had a complete positive response to the chemotherapy. However, three months after treatment he presented with shortness of breath and severe hypoxemia associated with peripheral eosinophilia. Computed tomography showed bilateral diffuse interstitial infiltrates that were refractory to antibiotic treatment. A lung biopsy showed eosinophilic pneumonia. He was subsequently treated with high-dose prednisone, resulting in a complete resolution of his symptoms and lung infiltrates.
This case illustrates that eosinophilic pneumonia may be a late sequela of bleomycin toxicity, and may respond dramatically to steroid treatment.
化疗药物博来霉素所致的肺部毒性包括多种病理变化,如闭塞性细支气管炎伴机化性肺炎、间质性肺炎和进行性间质纤维化。我们报告一例罕见的与博来霉素相关的嗜酸性粒细胞性肺炎病例。
一名44岁的西班牙裔男性,患有原发性纵隔精原细胞瘤并伴有上腔静脉综合征,接受了四个周期的博来霉素、依托泊苷和顺铂治疗。他对化疗有完全的阳性反应。然而,治疗三个月后,他出现了呼吸急促和严重低氧血症,并伴有外周血嗜酸性粒细胞增多。计算机断层扫描显示双侧弥漫性间质浸润,对抗生素治疗无效。肺活检显示为嗜酸性粒细胞性肺炎。随后他接受了大剂量泼尼松治疗,症状和肺部浸润完全消退。
该病例表明嗜酸性粒细胞性肺炎可能是博来霉素毒性的晚期后遗症,且可能对类固醇治疗有显著反应。
