Gold lung.

A rare syndrome of acute pulmonary damage due to gold therapy is described. It appears to be an entity separate from the usually reported side-effects of gold. It has a good prognosis, responding to the cessation of gold and to corticosteroid therapy. Apart from this syndrome of acute pulmonary damage, there is, as yet, no convincing evidence to incriminate gold as a cause of other pulmonary manifestations which have been attributed to rheumatoid arthritis.
