Case ReportsHypersensitivity pneumonitis due to inhalation of fungi-contaminated esparto dust in a plaster worker.
Hypersensitivity pneumonitis or extrinsic allergic alveolitis can be defined as a lung disease caused by a wide group of antigens that reach the lung by inhalation of organic and/or inorganic dust of various sources. The esparto (Stipa Tenacissima and Ligeum Spartum) is an herbaceous of the grass family used in the production of ropes, canvas, sandals, mats, baskets, and so forth. It is also used in the construction industry for the production of paper paste. ⋯ We present a case of occupational hypersensitivity pneumonitis in a plaster worker. Clinical findings, precipitating antibodies, and evolution, after having removed him from his work, confirmed the diagnosis. In our case, Aspergillus species contaminating esparto are probably the antigens that caused the disease.
