A 60-year-old man, employed as a welder for 25 years, was admitted with an abnormal shadow on chest X-ray. An ill-defined and solitary mass shadow 3 cm in diameter was subsequently detected in the left upper lung field. The mass shadow exhibited high attenuation on chest CT scan. Transbronchial lung biopsy (TBLB) revealed an organized lesion possessing a large quantity of iron. Although pneumoconiosis was suspected, the possibility of lung cancer could not be dismissed. Pneumoconiosis (welder's lung) was diagnosed after thoracotomy and examination of the resected mass. Pneumoconiosis (welder's lung) rarely presents as a solitary mass lesion.
一名60岁男性，从事焊工工作25年，因胸部X光检查发现异常阴影入院。随后在左上肺野发现一个直径3厘米、边界不清的孤立性肿块阴影。胸部CT扫描显示该肿块阴影呈高密度。经支气管肺活检（TBLB）显示为一个有大量铁的机化性病变。虽然怀疑是尘肺病，但肺癌的可能性也不能排除。开胸手术并对切除的肿块进行检查后诊断为尘肺病（焊工肺）。尘肺病（焊工肺）很少表现为孤立性肿块病变。
