Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis, is a complex syndrome caused by exposure to a wide variety of organic particles small enough to reach the alveoli (<5 μm). In susceptible individuals, these antigens provoke an exaggerated immune response of the small airways and lung parenchyma. The causative antigens include fungi; bacterial, protozoal, animal or insect proteins; low–molecular-weight chemical compounds etc among others. In this report, we describe the case of a 42 year old healthy gentleman, who developed acute hypersensitivity pneumonitis with respiratory failure following exposure to soldering fumes. He was treated with supplemental oxygen, systemic steroids and supportive measures. After clinical response, he was advised avoidance of further exposure. He remains asymptomatic and under follow up.
Keywords: Hypersensitivity pneumonitis, soldering, occupational lung disease.
