Abstract
Abstract
Background
Welding which as performed regularly by more than a million workers worldwide is associated with exposures to irritative, fibrogenic and carcinogenic fumes and gases.
Methods and Results
We present the case of a welder who had worked under extremely poor hygiene conditions for nearly 20 years and had developed end-stage lung fibrosis, finally requiring lung transplantation. Detailed histopathology and Scanning Electron Microscopy/Energy dispersive x-ray spectroscopy (SEM/EDS) analysis of his lungs showed advanced interstitial fibrosis and dust deposits in the lungs and in peribronchial lymph nodes containing welding type bodies, Fe, Si (silica), Ti (titanium), SiAl (aluminum silicates), Fe with Cr (Steel), Zr (Zirkonium).
Conclusion
Due to these severe findings, the absence of a systemic disorder and the failure to meet the criteria for diagnosis of idiopathic pulmonary fibrosis (IPF), the most likely diagnosis of this case is welder’s lung fibrosis.
