Pulmonary siderosis is a pneumoconiosis caused by chronic iron inhalation. A diagnosis of pulmonary siderosis is based on a patient history of iron inhalation, on chest radiographic findings, and on accumulation of iron oxide in macrophages within the lung. A typical radiographic finding of pulmonary siderosis includes ill-defined micronodules that are diffusely distributed in the lung. We experienced a 52-year-woman with a $1.3{\times}1.5$-cm mass in the left upper lobe with multiple nodules in both lungs. Because the radiographic findings were atypical, we conducted a video-assisted thorascopic lung biopsy procedure to exclude the diagnosis of metastatic lung cancer. After confirming iron deposition in the lung tissue and knowing the patient's occupational history of welding iron, we concluded that this was a case of pulmonary siderosis.

철폐증은 철분진을 장기간 흡입하여 발생하는 질환으로, 진단은 환자의 용접등의 철분진에 대한 노출력과 흉부 방사선 소견과 함께 폐내 철분진의 축적을 확인한다. 저자들은 기관지 폐포 세척술 및 경피적 폐생검술을 시행하여 철폐증을 진단한 1예를 경험하였기에 보고하는 바이다.

Pulmonary siderosis, or Welder's lung disease is an occupational lung disease caused by iron-inhalation. Diagnosis of pulmonary siderosis is based on occupational history of the patient, radiologic findings, and pathologic findings of iron-laden macrophages within lung tissue or broncho-alveolar lavage fluid. We observed a case of a 43 years-old welder diagnosed with pulmonary siderosis via thoracoscopic lung biopsy. Sputum culture along with pathology also identified a non-tuberculotic mycobacterial infection with a sputum culture and the pathologic findings. The patient was treated with anti-tubercular medication and cessation of iron-exposure. And his condition improved within a few months.
