[Espartosis. A new type of extrinsic allergic alveolitis among construction plasterers].

The clinical characteristics of three plasterers in contact with esparto and who presented a picture of extrinsic allergic alveolitis which was peculiar because of their being hyperacute and causing hypoxemia. In addition to a review of 5 previously published sporadic cases the clinical picture of this new type of apparently infrequent alveolitis is described. The causal antigen is unknown although contamination by fungus or the addition of raw esparto may be the origin of the disease. After a review of the literature regarding this subject, the authors suggest that, in addition to cases of asthma and chronic airway obstruction, the patients with extrinsic allergic alveolitis be included under the name of espartosis following esparto dust inhalation.
