Rheumatoid disease in the larynx and lung.

Visceral manifestations of rheumatoid disease have recently received considerable attention. Lesions in the larynx, lung, and heart are of clinical importance. The object of this paper is to report one example of severe laryngeal involvement and another with unusual pulmonary lesions. The histochemical properties of these lesions are compared with those of a histologically typical rheumatoid nodule.
