Inflammatory pseudotumors of the lung are uncommon and etiologically diverse lesions that often present as solitary masses in the lung. It may be difficult to distinguish these lesions from more commonly encountered lung neoplasms. Inflammatory pseudotumors can also occur in other organs, but the lung is most commonly involved. We describe a 63-year-old male coal miner with a 40-year history of dust exposure, who had a large right middle lobe mass on chest roentgenograms, with slow growth over the 7 years prior to admission. Repeated transthoracic echo-guided biopsies of the mass were indicative of an inflammatory and reactive process. The radiographic, histologic, and clinical findings indicated a diagnosis of inflammatory pseudotumor. The patient refused surgical intervention and was regularly followed at our outpatient clinic. Follow-up chest roentgenograms for 1 year revealed that the tumor size was stable. This case suggested that inflammatory pseudotumor, although uncommon, should be included in the differential diagnosis in a patient with pneumoconiosis and a solitary mass in the lung.
肺部炎性假瘤并不常见，病因多样，常表现为肺部的孤立性肿块。这些病变可能难以与更常见的肺部肿瘤相区分。炎性假瘤也可发生于其他器官，但肺部最为常见。我们描述了一名63岁男性煤矿工人，有40年粉尘接触史，胸部X线片显示右中叶有一巨大肿块，入院前7年生长缓慢。对该肿块反复进行经胸超声引导下活检，结果提示为炎症和反应性过程。影像学、组织学和临床检查结果均表明诊断为炎性假瘤。患者拒绝手术干预，在我们的门诊定期随访。随访1年的胸部X线片显示肿瘤大小稳定。该病例提示，炎性假瘤虽不常见，但在尘肺病患者且肺部有孤立性肿块时，应列入鉴别诊断。
