Even in the twenty-first century, welding is still a common and a highly skilled occupation. The hazardous agents associated with welding processes are acetylene, carbon monoxide, oxides of nitrogen, ozone, phosgene, tungsten, arsenic, beryllium, cadmium, chromium, cobalt, copper, iron, lead, manganese, nickel, silver, tin, and zinc. All welding processes involve the potential hazards for inhalation exposures that may lead to acute or chronic respiratory diseases. According to literature described earlier it has been suggested that welding fumes cause the lung function impairment, obstructive and restrictive lung disease, cough, dyspnea, rhinitis, asthma, pneumonitis, pneumoconiosis, carcinoma of the lungs. In addition, welding workers suffer from eye irritation, photokeratitis, cataract, skin irritation, erythema, pterygium, non-melanocytic skin cancer, malignant melanoma, reduced sperm count, motility and infertility. Most of the studies have been attempted previously to evaluate the effects of welding fumes. However, no collectively effort illuminating the general effects of welding fumes on different organs or systems or both in human has not been published. Therefore, the aim of this review is to gather the potential toxic effects of welding fumes documented by individual efforts and provide informations to community on hazards of welding.

We present the case of a 45-year-old woman, working as a silver polisher since 11 years, complaining of dyspnea on exertion and dry cough. Intensive diagnostic workup, including high-resolution CT scan of the chest and lung biopsy by VATS led to the diagnosis of pulmonary siderosis. Pulmonary siderosis is a benign, non-fibrotic type of pneumoconiosis caused by inhalation of iron oxide, which is generally asymptomatic (except in concurrent smoking or concurrent silicosis). Combination of relevant exposure and the typical findings on CT-imaging (centrilobular nodules without cranio-caudal gradient) usually strongly suggest the diagnosis, but this should always be discussed at a multidisciplinary consultation. This includes discussing whether to perform a lung biopsy for histological confirmation. Cessation of the causative exposure is the only-treatment one can take and then radiological features can improve and even disappear of time. Unfortunately, this treatment has an enormous impact on patient's life because it implies changing profession. Preventive measures can be taken by employers (respiratory equipment and ventilation). This case illustrates that physicians should stay vigilant about occupational exposures in clinical practice as well as the need for multidisciplinary consult in patients suspected of having interstitial lung disease.
