A 45-year-old man was seen in consultation for evaluation of a spiculated right-lower-lobe mass that enlarged over 1 year. The patient had suffered accidental instillation of activated charcoal into the right lung via nasogastric tube 2 years prior to this consultation, with resultant respiratory failure, pneumonia, and pneumothorax. Biopsy of the mass showed anthracosis and granulomatous inflammation. A positron emission tomogram was strongly positive at the lesion, and right-lower-lobectomy with partial diaphragmatic resection was performed. On gross examination of the mass, a charcoal concretion was evident. Histologic examination showed intrinsic and surrounding granulomatous inflammation, but without tumor. The patient recovered uneventfully, and after 1 year had not experienced further complications.
一名45岁男性因右下叶毛刺状肿块就诊,该肿块在1年内增大。该患者在此次就诊前2年曾因鼻胃管意外将活性炭滴入右肺,导致呼吸衰竭、肺炎和气胸。肿块活检显示炭末沉着症和肉芽肿性炎症。正电子发射断层扫描显示病变处呈强阳性,遂行右下叶切除术及部分膈肌切除术。大体检查肿块时,可见明显的炭末结石。组织学检查显示内部及周围有肉芽肿性炎症,但无肿瘤。患者恢复顺利,1年后未出现进一步并发症。
