Rheumatoid arthritis and amyloid disease.

Introduction The greater part of the literature on the occurrence of amyloidosis in rheumatoid arthritis and in Still's disease comes from the Western Hemisphere. Since the recent publication in this country of such a case by Yeoman and Wilson (1947) the interest of rheumatologists on this side of the Atlantic has been awakened and a watch has been kept for further cases. Over 200 cases of rheumatoid arthritis have been seen in the Rheumatology Unit of the Royal Ftee Hospital, and its predecessor the British Legion Unit, during the past year and a half. Several cases have for one reason or another been suspected of suffering from coincident amyloid disease, but only in one case has the diagnosis been established beyond doubt. This case is reported below.
